People who aren't generally considerate of other people while driving. EX- Turning from the middle of the lane so no one can get by you. Making me pass you on the right because you feel like doing 75 in the fast lane, people that come to almost a dead stop before turning (terrible in South Jersey/Phili area), people who stop at a merge... It's not a yield, it's a fucking merge (Cause of my first accident, dude in front of me stopped, I stop behind him, Cadillac behind me didn't). And last, when I'm in the fast lane doing 85ish and an SUV or van comes up so fast that I barely have time to get right, then as they pass (at 90-100mph) I see Aladdin playing in the back for the guy's 3 kids who aren't buckled in.
People who bring babies to restaurants. There are a few children I have seen that actually are very well behaved but if there is a chance of your kid crying, leave them with a babysitter or stay home all together. And parents who let their kids "play" in a restaurant. Discipline your fucking kids, a restaurant is not the place for them to play. And the last one for restaurants, when 6 people sit down at my biggest table, the 2 babies have cheerios, one adult isn't eating, one is having a side salad, and 2 are getting real meals. So you just took my biggest table, and the bill might be forty bucks? Let your kids run around the restaurant some more, I just sprinkled AIDS on the floor and I'm tripping them when they run by.
Last one I can think of, when people at the gym take a very purpose built machine and use it for something completely else. EX- my brother was at the gym the other day and had to do squats. He goes to the one cage they have (they have machines but it's different) and a dude has dragged a flat bench over and is doing a bench press with next to no weight, without full extension either way, and is taking his sweet ass time in between sets.
The all encompassing thing in all the things that piss me off is a general lack of caring for anyone else but yourself. Your not fucking cool, your not fucking special, you're not your job. You're not how much money you have in the bank. You're not the car you drive. You're not the contents of your wallet. You're not your fucking khakis. You're the all-singing, all-dancing crap of the world... just like everyone else. Now get off your pedestal before I kick it over and smash you in the head with it.
