And I mean the nonreligious stuff. We talk about that all day long here. I'll start...
People who insist on turning against heavy traffic from the driving lane even though there is a middle lane set aside for turning.
People who can't take two additional seconds to push their shopping cart into the stacked carts, but leave it laying around two or three feet away from where it should properly be put.
Men who piss into toilets without putting the seat up and/or don't wipe the seat. (Were you raised in a barn or is it that you're afraid of the germs on the seat but are also afraid of washing your hands after touching something "dirty"?)
Otherwise intelligent people who can't pronounce "nuclear" without putting two u's in it.
