With its hat up and its wire out, Jeff wondered if the robot had really been in a position to think. He felt again a stab of sympathy. If that had been so, it must have been awful to be trapped inside a box, able to think but unable to get out. How long had it been there? It must have felt so helpless.

"Please," he said to the manager. "You're being too rough. Let me help you lift it out."

"Too rough?" said the manager with a sneer. "Nothing can hurt it. For one thing, it's too far gone."

He looked up at Jeff with an unpleasant expression on his face. "You signed that paper, you know. I told you it doesn't work right, so you can't back out. I don't think you can use it for teaching purposes because it doesn't have the attachments that will allow it to tie into the Education System. It doesn't even talk. It just make sounds that I can't make sense of."

Now, for the first time, something happened inside the barrel. The hatlike lid shot up and hit the shopkeeper in the shoulder as he was leaning over the box.

Underneath the lid was half a face. At least that's what it looked like. There were two big eyes-no! Jeff leaned across and saw that there were also two big eyes at the back -or maybe that was the front.

"Ouch," said the manager. He lifted a fist.

Jeff said. "You'll just hurt yourself if you try to hit it, sir. Besides, it's my robot now, and I'll have the law on you if you damage it."

The robot said in a perfectly clear voice that was a high and almost musical tenor. "That vicious man insulted me. He's been insulting me a lot. Every time he mentions me, he insults me. I can speak perfectly well, as you can hear. I can speak better than he can. Just because I have no desire to speak to my inferiors, such as that co-called manager, doesn't mean I can't speak."

The manager kept puffing out his cheeks and seemed to be trying to say something, but nothing came out.

Jeff said, quite reasonably, "That robot can certainly speak better than you can right now."

"What's more," said the robot, "I am a perfectly adequate teaching robot, as I will now demonstrate. What is your name, young man?"

"Jeff Wells."

"And what is it you would care to learn?"

"Swahili. The Martian Colony dialect-uh-sir." It suddenly occurred to Jeff that he ought to show a decent respect to a robot that clearly displayed a certain tendency to irascibility and shortness of temper.

"Good. Take my hand and concentrate. Don't let anything distract you."

The little robot's left-or possibly right-side dilated to a small opening, out of which shot an arm with a swivel elbow and two-way palms, so that it was still impossible to tell which was its front and which its back. Jeff took the hand, which had a pleasantly smooth, but not slippery, metallic texture.

"You will now learn how to say 'Good morning, how are you?' in Martian Swahili," said the robot.

Jeff concentrated. His eyebrows shot up, and he said something that clearly made no sense to the manager.

"That's just gibberish," said the manager, shrugging.

"No, it isn't," said Jeff. "I know a little Swahili, and what I said was Martian Swahili for 'Good morning, how are you?'; only this is the first time I've been able to pronounce it correctly."

"In that case," said the manager hastily, "you can't expect to get a teaching robot that's in working order for a miserable eighty-five-credits. "

"No, I can't," said Jeff, "but that's what I got it for. I have the paper and you have the money, and that ends it, unless you want me to tell the police you tried to sell an inoperable robot to a fourteen-year-old. I'm sure this robot can act inoperable if I ask him to."

The manager was puffing again.

The robot seemed to be getting taller. In fact, it was getting taller. Telescoping legs were pushing out of the bottom of the barrel, with feet that faced in both directions. The robot's eyes were now closer to the level of the little shopkeeper, who was a good head shorter than Jeff.

The robot said, "I would suggest, inferior person, that you return the eighty-five credits to this young man, and let him have me for nothing. An inoperable robot is worth nothing."

The manager shrieked and stepped back, falling over a stasis box containing a set of robot weeders. "That thing is dangerous! It doesn't obey the laws of robotics! It threatened me!" He began to shout. "Help! Help!"

"Don't be silly, mister," Jeff said. "He was just making a suggestion. And you can keep the eighty-five credits. I don't want them."

The manager mopped his brow again. "All right, then. Get it out of here. It's your responsibility. I don't ever want to see that robot again. Or you, either."

Jeff walked out, holding the hand of a barrel that had once contained Norb's Nails and had now sprouted two legs, two arms, and half a head.

"You've got a big mouth," said Jeff.

"How can you tell?" said the robot. "I talk through my hat."

"You sure do. What's your name?"

"Well, Mac-that was McGillicuddy-called me Macko, but I didn't like that. Mac and Macko sounds like a hyperwave comedy team. But at least he referred to me as 'he' instead of 'it.' That was something, anyway. It showed respect. What would you like to call me, Jeff?"

Jeff should have corrected the robot. All robots were supposed to put a title before a human name, but it was clear that the robot he had didn't follow customs too well, and Jeff decided he didn't mind that. Besides, he would get tired of being called Master Jeff.

He said, "Have you always been inside a barrel of Norb's Nails?"

"No, only since McGillicuddy found me; that is, since he repaired me. He was a genius at robotics, you know." Then, with obvious pride, the robot added, "The barrel is part of me, and I won't wear out. Not ever!"

"Oh, I don't know," said Jeff coolly. "Your label just fell off."

"That's because I don't need a label. This old but serviceable barrel doesn't contain nails any longer. It contains me. I like this barrel. It's good, strong stainless steel."

"All right," said Jeff. "In that case, since this wonderful barrel once held Norb's Nails why don't I call you Norby?"

The robot blinked and said, "Norby…Norby…," as though he were rolling the sound round on his tongue and tasting it-except that he didn't have a tongue and probably couldn't taste. Then he said, "I like it. I like it very much."

"Good," said Jeff. And he and Norby walked off, still hand in hand.

The housekeeping computer, not having feelings or much intelligence, didn't disapprove of Norby. That relieved Jeff, who realized that he should have known that the housekeeper would not give him anything to worry about, and would, in fact, be incapable of doing so. Of course, the housekeeper didn't approve of Norby, either, but that didn't matter.

Now that he was home and could relax, Jeff surveyed his purchase critically. "Does your head come out of the barrel any further, Norby?"

"No. This is all there is of my head. It's all I need. It's all anyone needs. Does it matter?"

Jeff studied Norby's large, oddly expressive eyes. "I guess it doesn't, but how do you get repaired? Do you come out of the barrel?"

"Certainly not. There's no me to come out of the barrel. it's part of me now. Mac welded me in so tightly, this barrel is my armor, my skeleton. Do you get out of your bones when you see the doctor? Come out of the barrel indeed!"

"Don't get mad about it. I'm just asking. How do you get repaired? Let's face it, Norby, I can't afford much in the way of maintenance, so I hope you're not planning on breaking down."

"If you're worrying about cost, Jeff, forget it. I will never need repairs. I am good at repairing other machines, but as you see me, I will always be." Norby whirled rapidly around on two quickly moving feet, but his eyes kept staring firmly at Jeff. Or the front two did-or was it the back two? "As you see, I work perfectly. Mac was a genius."
