No, Elaine, you are not petty. That would drive me nuts,too. I think flossing should be done in the bathroom. Eating in the livingroom while watching TV, while standing would drive me absolutely crazy!
My DH hangs his hooded sweatshirts on the doorstop of our entry in from the garage. It drives me crazy - I always tell him, "Why do your hang your coats there, it's not a closet or anything." Well, he just keeps doing it. His logic is that way he won't forget it in the morning.
When our garbage can gets full (we have an industsrial size one, since we have so many kids), I will mention the junk is getting full - and he will just go and push it down - he will do that until, I can't take it anymore - then, it is so tight in the can and heavy, I can barely get it out, much less tie the bag up!
Of course, he is a typical guy. He cannot watch TV more than 5 minutes - without changing the channel. He will go back and forth to 3, 4 or 5 games (hockey, football, baseball, basketball, and NASCAR). I know they invented the remote for men!
