Biggest Pet Peeve

I really have never given much thought to my pet peeves, but now that I think about it I can think of one that bugs me. It is when people leave their trash on the ground and walk away and forget about it. I am kind of a neat freak in a way and when people do that, especially my little sister, it bugs the hell out of me. I keep asking her why she does that and she doesnt give me a good answer. I think she does it just to tick me off. I guess I wouldnt go to great lengths to avoid it because I dont live at my house anymore so whatever stinky trash she leaves laying around is not my problem, and if it happened somewhere I was living, then I guess I would learn to live with it. Another couple pet peeves are lazy bums who dont do anything and expect people to just give them stuff and people who are so cheap that they wouldnt even drive a couple miles down the road if their friend was freezing to death just because gas is too expensive.
