I ALWAYS close/lock etc doors and windows of the my car and other's after mine was brocken into, there for i EXPECT them to do the smae in my car.
My friend often opens the window and as i drop her off she says "shall i close/lock it if i say yes she does if i say dont bother then i will, but she ask's so its ok if she doesnt.
But that same friend litter's my car, puts feet on dash board, puts feet on seats (i brought expensive seat covers), lets dirty hair dog on seats, THIS IS NOT ACCEPTABLE, she would not like it if i did that in her car, in fact she would go mentle.
IT bugs me if the car is clean when you enter it clean your mess up when you leave better still dont make mess.
