wtf

Why is it that if I go around to the bathroom and laundry room trash cans and empty them all into one bag it's my job to take that bag to the trash, but if someone else empties them all into one bag and then sets it on the floor then the least I can do is take it the rest of the way to the trash? Tom left a bag of lint and tampons in front of my bathroom sink a week ago and wonders why I use his sink now.
