Well, this morning another mom, whose child also attended this preschool, stopped me on the yard with the following information:
Other Mom: I had to help (your child) get dressed yesterday. He started taking his clothes off on the yard and I stopped him and said "I think we're supposed to leave our clothes on here."
Me: Oh, man, it was just a matter of time...
Other Mom: And he asked me "are you sure?" so I had to ask his teacher if you're supposed to keep your clothes on in Kindergarten; she said you were.
Me: How far did he get?
Other Mom: He got his shirt off and was just about to take off his pants when I stopped him.
That's my boy!
