[Off the top of my head. Not necessarily in order of dislike.]
1. Flip Flops (these are not good for your feet, people. Okay at the pool, bad for walking around.)
2. Matt Hardy (He is soooo boring -- why do people like him? in addition to hating his dumb wrestling moves, I also hate his hair, his facial hair, and his pants.)
3. Unnecessary abbreviations, both spoken and written. We have enough time to just say the complete names of people, couples, films, and events, and to spell out every letter of our words. Believe me.
What do you hate?
Tomorrow: three things I love.
