People who can't stay in one lane when they're driving. They meander from lane to lane, riding the center line...and making me very nervous.
People who have never been to the US, and who's only knowledge comes from what they see on TV or read in the paper...but who think it's ok to slam pretty much everything this country does and says, all the while declaring their country to be morally, intellectually, socially and democratically superior. It's ok to hate the US. Everyone is entitled to do that (and that's another great thing about America, you can say you hate it here without fear of persecution or reproach) - but to constantly point out what we as a nation are doing wrong despite the fact that they have never been here...that really pisses me off.
People who apologize, but do so on their terms. "I'm sorry for what I said, but you did deserve it"....yeah. You can take that and shove it where the sun doesn't shine. Apologize, and do so meaningfully, or don't bother. Anything less is just for show, and is ultimately an exercise in stroking your own ego.
Elderly drivers. Bless them , I'm glad that they're getting around unassisted...but darn it, some of them are downright dangerous. I think that there should be a new rule - if you can't find the bathroom in your own home, or if you can't remember your own name some days, then you shouldn't be allowed to hold a driver's license.
Squirrels. I like them, they're cute and all...but they've gnawed through the lid if my garbage can and have started to fling poo at me when I'm in the yard. I'll be glad when the dog gets here - then again, the squirrels are bigger than he is, so perhaps he'll be the one getting terrorized!!
I have more, many more...but I have to go feed the family. I'll be back.....
