Am I THAT hateable?

There's this girl at school named Mandie who does not like me. I know this because she is friends with my friend Jay and has informed him about this. This fact never bothered me though. I'm not too fond of the girl either. She hasn't done anything to me personally, but I just consider her to be a bit of a bitch and she's also quite annoying.
So I'm in my economics class today and she sits about a couple seats in front of me and was talking to Jay. I didn't hear what they were talking about, until I heard Mandie say, "I don't know why , I just don't like anything about her; her hair, face, nose...nothing." I felt that she was talking about me, but I have no proof of this so I kind of forgot about it. Next period, Jay comes up to me and asks,"Did you hear what Mandie said about you in economics?" "Oh." I replied. "She WAS talking about me, eh?" Yeah, somehow my name had gotten brought up in their conversation and Mandie stated that she hated me. Jay questioned her about this, and she couldn't come up with a legitimate reason for hating me. She just hated EVERYTHING about me; my attitude, hair, face, and nose...just everything! Now, I can kind of understand why she might find me UNLIKEABLE because of my attitude. My sense of humour is very mean and a lot of people don't realize it's sarcasm. But, I never say anything to Mandie, never talk to her, and she's never around me to hear me say anything mean. So, it just kind of pisses me off that she says she hates me...especially the fact that she hates EVERYTHING about me. I mean, there are always those people you don't care for, that's just how the world works. But hate??? Hate's a pretty strong thing. Oh well, it doesn't really bother me. Her friendship or any sort of liking of me from her is not a loss. She's just a stupid, fat bitch who will get pregnant from her bf with benefits and she'll go nowhere in life. : )
