One of my biggest pet peeves is seeing the lid of my toilet seat left up by others when I go into the bathroom. If you don't use the lid for the purpose for which it's intended (to put it down, why else does it exist otherwise?) then you do not have the right to complain that you keep dropping things in the toilet! Otherwise, why don't we just leave the door to the dishwasher open, the bag of catfood open so that we stink up the place, and leave the front door open so we can say "Hey come on in and check out my open toilet!" After all, it is attractive that way.
