I used to live down a dirt road and I rarely washed my previous car because it would just get dirty the first time I left the house. Well, one evening I was at Wally world and when I came out I saw where someone had written "wash me" on the back window and on the side doors. I washed the car the next day and guess what.....where they wrote "wash me" was scratched into the paint. That really pissed me off.
Why can't people leave stuff that isn't there's alone. Or walk along their car, not someone else's.
