He's in Kindergarten and got a note sent home (that I have to sign and return) telling me that after recess (he goes all day, every other day), he had sand in his shoe, which he proceeded to take off, and dump over a classmate's head.
I had a hard time keeping a straight face talking to him about it and telling him it is never ok to do that, etc.
Even DH found it more funny than anything.
Oy, we have our own little Bart Simpson. DH assures me that he did stuff like this and worse at the same age.
