Someone who has made your life hell, or treated you like shit.
And the award goes to.....................................my college roommate. Well, one of the 11. Every time I lived with roommates, there were always at least 3 of us (for two years there were 4) and there was always one that things would go sour with eventually. I guess that's what happens when there's a bunch of chicks living together.
This specific roomie was an exception. It wasn't the usual roommate issues that drove us apart, it was much more. We became friends when she still lived in the dorms, and things were good for a time, but over that time I started to notice things. And then she treated me worse, and worse until I just couldn't deal with her and her issues anymore. It was hurting me to continue letting her be a part of my life. I really cared about her, but her actions showed she didn't give a shit about me in return.
I wrote this really long, drawn out narrative of her damage to me, but then I decided, she doesn't deserve a long post.
She is no longer in my life for a reason, and my life is that much better without her.
