Underpants

Why do boys of all ages leave underpants in the middle of the floor? Are they dirty? If so, disgusting. Are they clean? If so, you, boys, are lazier than previously suspected. I just found a pair of J's undies drooping over one stair about 75% of the way up the case and a pair of T's near but not too near our hamper. Is this another empty-OJ-bottle-back-in-the-fridge trick? Deep, existential musings on this Thursday.
