conversations with a preschooler

On the way home from preschool today Luke and I had the following conversation:

L:  Did you ask my teacher how I was today?
M:  No, would you like me to ask you how you were in school today instead?
L:  Oh, yes!
M:  Okay.  Luke, how were you in school today?
L:  after a lengthy pause and a confused look..."Mom, that was kind of a dumb question.  I don't know how I was at school today, you have to ask my teacher."
