My last night of childhood began with a visit home. T'Gatoi's sisters had given us two sterile eggs. T'Gatoi gave one to my mother, brother, and sisters. She insisted that I eat the other one alone. It didn't matter. There was still enough to leave everyone feeling good. Almost everyone. My mother wouldn't take any. She sat, watching everyone drifting and dreaming without her. Most of the time she watched me.

I lay against T'Gatoi's long, velvet underside, sipping from my egg now and then, wondering why my mother denied herself such a harmless pleasure. Less of her hair would be gray if she indulged now and then. The eggs prolonged life, prolonged vigor. My father, who had never refused one in his life, had lived more than twice as long as he should have. And toward the end of his life, when he should have been slowing down, he had married my mother and fathered four children.

But my mother seemed content to age before she had to. I saw her turn away as several of T'Gatoi's limbs secured me closer. T'Gatoi liked our body heat, and took advantage of it whenever she could. When I was little and at home more, my mother used to try to tell me how to behave with T'Gatoi how to be respectful and always obedient because T'Gatoi was the Tlic government official in charge of the Preserve, and thus the most important of her kind to deal directly with Terrans. It was an honor, my mother said, that such a person had chosen to come into the family. My mother was at her most formal and severe when she was lying.

I had no idea why she was lying, or even what she was lying about. It was an honor to have T'Gatoi in the family, but it was hardly a novelty. T'Gatoi was not interested in being honored in the house she considered her second home. She simply came in, climbed onto one of her special couches and called me over to keep her warm. It was impossible to be formal with her while lying against her and hearing her complain as usual that I was too skinny.

"You're better," she said this time, probing me with six or seven of her limbs. "You're gaining weight finally. Thinness is dangerous." The probing changed subtly, became a series of caresses.

"He's still too thin," my mother said sharply.

T'Gatoi lifted her head and perhaps a meter of her body off the couch as though she were sitting up. She looked at my mother, and my mother, her face lined and old-looking, turned away.

"Lien, I would like you to have what's left of Gan's egg." "The eggs are for the children," my mother said.

"They are for the family. Please take it."

Unwillingly obedient, my mother took it from me and put it to her mouth. There were only a few drops left in the now-shrunken, elastic shell, but she squeezed them out, swallowed them, and after a few moments some of the lines of tension began to smooth from her face.

"It's good," she whispered. "Sometimes I forget how good it is."

"You should take more," T'Gatoi said. "Why are you in such a hurry to be old?"

My mother said nothing.

"I like being able to come here," T'Gatoi said. "This place is a refuge because of you, yet you won't take care of yourself."

T'Gatoi was hounded on the outside. Her people wanted more of us made available. Only she and her political faction stood between us and the hordes who did not understand why there was a Preserve—why any Terran could not be courted, paid, drafted, in some way made available to them. Or they did understand, but in their desperation, they did not care. She parceled us out to the desperate and sold us to the rich and powerful for their political support. Thus, we were necessities, status symbols, and an independent people. She oversaw the joining of families, putting an end to the final remnants of the earlier system of breaking up Terran families to suit impatient Tlic. I had lived outside with her. I had seen the desperate eagerness in the way some people looked at me. It was a little frightening to know that only she stood between us and that desperation that could so easily swallow us. My mother would look at her sometimes and say to me, "Take care of her." And I would remember that she too had been outside, had seen.

Now T'Gatoi used four of her limbs to push me away from her onto the floor. "Go on, Gan," she said. "Sit down there with your sisters and enjoy not being sober. You had most of the egg. Lien, come warm me."

My mother hesitated for no reason that I could see. One of my earliest memories is of my mother stretched alongside T'Gatoi, talking about things I could not understand, picking me up from the floor and laughing as she sat me on one of T'Gatoi's segments. She ate her share of eggs then. I wondered when she had stopped, and why.

She lay down against T'Gatoi, and the whole left row of T'Gatoi's limbs closed around her, holding her loosely, but securely. I had always found it uncomfortable to lie that way but, except for my older sister, no one else in the family liked it. They said it made them feel caged.

T'Gatoi meant to cage my mother. Once she had, she moved her tail slightly, then spoke. "Not enough egg, Lien. You should have taken it when it was passed to you. You need it badly now."

T'Gatoi's tail moved once more, its whip motion so swift I wouldn't have seen it if I hadn't been watching for it. Her sting drew only a single drop of blood from my mother's bare leg.

My mother cried out—probably in surprise. Being stung doesn't hurt. Then she sighed and I could see her body relax. She moved languidly into a more comfortable position within the cage of T'Gatoi's limbs. "Why did you do that?" she asked, sounding half asleep.

"I could not watch you sitting and suffering any longer." My mother managed to move her shoulders in a small shrug. "Tomorrow," she said.

"Yes. Tomorrow you will resume your suffering—if you must. But for now, just for now, lie here and warm me and let me ease your way a little."

"He's still mine, you know," my mother said suddenly. "Nothing can buy him from me." Sober, she would not have permitted herself to refer to such things.

"Nothing." T'Gatoi agreed, humoring her.

"Did you think I would sell him for eggs? For long life? My son?"

"Not for anything," T'Gatoi said stroking my mother's shoulders, toying with her long, graying hair.

I would like to have touched my mother, shared that moment with her. She would take my hand if I touched her now, freed by the egg and the sting, she would smile and perhaps say things long held in. But tomorrow, she would remember all this as a humiliation. I did not want to be part of a remembered humiliation. Best just to be still and know she loved me under all the duty and pride and pain.

"Xuan Hoa, take off her shoes," T'Gatoi said. "In a little while I'll sting her again and she can sleep."

My older sister obeyed, swaying drunkenly as she stood up. When she had finished, she sat down beside me and took my hand. We had always been a unit, she and I.

My mother put the back of her head against T'Gatoi's underside and tried from that impossible angle to look up into the broad, round face. "You're going to sting me again?"

"Yes, Lien."

"I'll sleep until tomorrow noon."

"Good. You need it. When did you sleep last?"

My mother made a wordless sound of annoyance. "I should have stepped on you when you were small enough," she muttered.

It was an old joke between them. They had grown up together, sort of, though T'Gatoi had not, in my mother's lifetime, been small enough for any Terran to step on. She was nearly three times my mother's present age, yet would still be young when my mother died of age. But T'Gatoi and my mother had met as T'Gatoi was coming into a period of rapid development—a kind of Tlic adolescence. My mother was only a child, but for a while they developed at the same rate and had no better friends than each other.
