When people say 'cookie' instead of 'biscuit'.
Mimes.
The fleas on my flatmates cat.
Clowns.
Takeaways that close at 8pm when everyone I know eats dinner later than that.
Lag.
The smell of peanut butter.
The hot weather forcing me to leave my window open so the cat can sleep on my bed.
Early closing gyms.
Getting bitten by fleas while trying to sleep.
Edit: Hey, i'm full of hate!
