Ok here's one that definitely ticks me off...
Long story time:
Whenever I was in high school, there was this girl who was just flat-out gross. She did more drugs than you can count, never bathed, and wore the same clothes for weeks at a time because she seriously thought that being trashy and unclean made her "hardcore". So anyhow, she had a realllllly bad attitude and a seriously disproportionate superiority complex (she actually said "Man, all of you losers SUCK because you want to be me so bad, it's pathetic."... yeah right

). She had no problems letting everyone know that she thought she was better than everyone else, and started problems with just about everyone, even if she didn't even know them.
Well, I happened to be one of those people, and for some reason she took a special liking to me. Keep in mind I have still TO THIS DAY never even talked to her, so she has no reason to not like me. Anyhow, she left threatening comments on my blog calling me childish names, and even made an entire website with my picture saying "OMG look how ugly she is, she needs to die soooo bad!"
It never really bothered me because I never let it bother me whenever someone hates me for no reason. Usually it just means they're jealous anyhow. Regardless, it was irritating that someone would go to such great lengths just to try to get to someone.
Well, that was in high school. I thought that after we graduated, we'd all be able to be adults and move on and whatnot, until the other day whenever I saw her at a party at my neighbor's house. I decided to just not say anything to her because I figured if I didn't give her reason to, she'd just mind her own and we'd go on an unspoken agreement to dislike each other quietly.
But NOOOOOOO. That's giving this girl WAY too much credit.
Immediately she starts in on me for no reason lol! It's to the point where it makes me laugh anymore because if someone is going to be THAT immature and hate someone they've never even talked to, then so be it. There is no changing her mind.
So I ignored her the whole time she was at this party literally making a jerk out of herself because she had crashed the party anyhow and it was full of my friends who already know she is stupid. Still, that didn't stop her from trying her hardest to (unsuccessfully) get people to laugh at me for things that weren't even embarrassing or funny, such as "Omg, she's wearing a HOODIE?! How dumb is THAT?" To which everyone was like "Yeah... um... everyone is wearing one. It's cold out here."
So when people weren't laughing at me like she wanted, she started talking to people around the party. Whenever they'd ask "What's your deal with Kristi?" to her, she'd make up some story about how I was "sooo mean to her back in high school." Realize she said this whenever I have literally never spoken a word to her in high school or otherwise.
So anyhow, now she's stalking me on the internet again. I swear, this girl never gives up. I'm almost positive that it's because she's jealous of me, though, because she's always wanted to be a model ever since high school, and never got to be one because she ruined her body with drugs and afterward (I'm assuming after she got off of the drugs) ended up gaining tons of weight. I'm thinking she's hates me now more than ever because I'm a model and haven't ruined myself like she has, not to mention she had a kid not too long ago, and while it's not really a bad thing to most people, to Ms. Selfish, it "ruined her life" and sadly she even
purposely tried to kill it while she was pregnant by doing more drugs than ever. She's bitter now that she's messed up so bad and taking it out on me, her only remaining target.
It's mildly annoying at best, and it doesn't really tick me off anymore I guess, but it DOES suck being stalked and harassed like that.
I'm sorry this is so long lol... I told you it was going to be a lengthy story. But I'm pretty sure this girl needs to drop off the face of the earth.
