L.H.
I guess it must be a boy thing! When my son was 3 he had an "accident" (!) in the back area of the minivan (not in his seat -- standing up in the cargo area!), all over the groceries! And when he would get put in time-out, he would take it out on me by peeing all over his bedroom floor (just finally got the carpet replaced!).
Guys' obsession with that part of the body and what they can do with it sure starts early, doesn't it????
Love your attitude. Enjoy those little peeing boys!
