I always have my car windows up while listening to music in the car for the same reasons stated above.
If I do a shitty job of parking my car, I back out of my space and do it again, correctly.
When I'm shopping at a record store, if I was carrying a CD because I was planning on buying it, but then changed my mind, I put it back in its correct place.
If I'm pissing at a public toilet, I lift the seat up, because people who piss all over the seat and don't clean it up should be drug out into the street and shot.
