Mommy and Daddy don’t think that I know, but I listen from under the table sometimes, and I heard them say it. When we leave the Institute today, it will be the last time I say good-bye to Priscilla, Dr. Warren, and the others. I’m glad we are leaving. I don’t like Dr. Warren’s infirmary. I don’t like the beds or the lights or the sounds.We live at the Institute on an Open floor, and Mommy and Daddy work in the field. Priscilla lives on a Closed floor with Dr. Warren. I only see her when we have our suits on, or when she’s behind a safe wall, but that’s still too close for me. She’s pale as a fish belly, and mean. So when Mommy says it’s time to go to school today, and today is a Father John day and not a Sister Mary Margaret day, I pick up my schoolbag and I wave at Priscilla through the safe wall, and when Mommy isn’t looking, I stick my tongue out at Priscilla before we leave. That makes me feel good.When I go say good-bye to Dr. Warren, I duck down real low so I don’t have to look him in the face.
