Bedtime

We had a babysitter watch the boys last night while Aba and I went out. I told the boys in advance. ZB (4 1/2) told me to tell the babysitter that his bedtime was 10:00. When I told him I wouldn't and that I don't want him up that late, he told me not to tell her when his bedtime was and he would tell her it was 10:00.
