Or maybe use something other than a tube that will work?” Mama took an extremely long time thinking for her, at least a whole second. “There are four water tanks on the ship and two tanks of water would be sufficient for the remainder of our journey. I can modify a water tank for incubation.” I asked, “Are you sure? Will it be safe? Will it be big enough for eight?” “The water tanks are made of the same materials as the incubation cylinders and have a capacity of eighty thousand liters. That will be sufficient for up to twenty infants.” If it weren’t for our breathing tubes, we would have sighed in relief. Girl said, “That’s GREAT!

We invited Boy and Girl to live with us several times, but they always declined and wouldn’t explain why. I hypothesized they were doing something they didn’t want us to see. When we were about seven years old, one morning we woke up with air hoses in our mouths and feeding tubes in our noses, as our parents had told us. A few days later my brother Escape started a competition for who could make the biggest poop cloud. We all tried to hold our bowels as long as possible, then turn in a circle as we let fly.
