Thanks everyone for the answers to my silly question. I guess I got the answers I was looking for. Most seem to think like I do, but there are a few that think as he did, so I guess he's like them and really felt it was not his job to roll up the window.

Leason learned: not everyone thinks like we do. lol Like I shouldn't have known that already.

I still stand behind that we should have been able to say something to him, without him getting upset. You should be able to talk to your friends and say " Hey, silly you left the window down and it rained in the car, next time try to remembed to roll it up" He didn't get mad when I yelled at him for leaving the gate open and letting Tuffy out. He said he was sorry, Why should this be any different.

Oh well, everythings fine now, he just pulled up a few minutes ago, wanting the oil changed in is bike. So I guess everythings back to normal again and I willing to bet that he rolls up the window from now on. LOL Shoot, without us he'd have no running car or bike, he can't afford to stay mad to long.
