Oy, I dislike many things. There aren't so many things I "hate", though. Hate is such a strong word... it just leads to more hating, and more hating after that; it's no good.
But some of the things I really dislike are :
- Vanity
- Arrogance
- Hypocrisy
- Narrow-mindedness
- Prejudice
- Imperialism - Like it's not out there...
- Being hungry - Yes, I know... but man, I get all upset when I'm hungry. It's so not funny

- Noise when I'm reading - I just can't read with noise
- People turning the lights on when it's dark all of a sudden - It hurts my eyes -_-;
- Wrinkled clothes
- Tomatoes!

- Telemarketers
- Being in a room with too many people - x_x
And I can keep going and going, but I'll just leave it with the thing I do, in fact, currently hate :
Summer - The sun should go to hell.
