1. People who shoot down entire genres of music before even listening to any band from it. If you tried some and didn't like it fine, but listen to it before you shoot it down.
2. Teenagers who think that they can say or do whatever they want. I am a teenager and therefore I know a lot of people like that. You may think you're the best at everything, but show some respect to those who actually do know more than you.
3. Those people who complain about the price of gas, but drive Hummers.
4. Text message writing. When I send a text message I spell almost everything out. If I run out of characters I'll go back and shorten you to u or in to n if i really need letters i'll do bcuz or b4, etc. I really hate to do that though because it's hard to read.
