Fight with the boyfriend? Snap at me.
Bad day at school? Snap at me.
Sometimes in the mornings I say: "Good morning" and I might as well have spoken to the wall, since I get absolutely no reply.
I've stopped saying "hello" and "how are you?" since she has the uncanny ability of making people feel invisible.
Considering that she's ALWAYS fighting with her boyfriend and ALWAYS having a bad day at school, let's just say I live with a person who's miserable 24/7 who you better not bump into in the hallway; otherwise she'll bite your head off.
I guess things could be worse; but going to law school is stressful enough w/o having to live with a such a moody person.
