Where do Teachers live?

Earlier today we had to stop at target and get a gift on the way to another kiddie party. Running to target on a Saturday AM is always a dicey proposition with any child. So I hustle him in, rush through and we are about to leave when we see his teacher. I talk to her for a few minutes and he is just staring in disbelief and answering her but in a shocked way. So she walks away, I bring G in the change his diaper, and we start with 20 questions. "Mommy, Why is Miss C in target? Why isn't she at school? Why doesn't she want to be my teacher anymore? Why does she have a car? Why does she have kids?" and on and on. Apparently, G thought his teachers LIVED at school. all the time. I guess that makes sense for a 3 year old mind. So after a long while, he finally got that she didn't live at school, she did still like him and his friends, and she was still going to be his teacher.
