Liars, cheats, people that walk really slow, when people stand on the back of your shoe, when people push in front of you in the line, when I can't get comfortable, flys, wasps, seagulls, moths, the wind.
Guys who try to use the “Are you on your period?” as way to end an argument always amuse me. Because it gives me the excuse to lean in close and whisper. “I started my day by waking up in a pool of my own blood. Is that how you’d like me to end yours?”^^^
