give your toe plenty of time to heal. dont rush into any surgery. surgery could make it worse.

Yeah, something tells me she feels guilty but is just too much of a coward to apologize for it. Back in June I had a conversation about it with her via text messages. First, I just asked her if she remembered slamming my toe. Initially, she said "Yes, why?" Then, about a minute later (while I was writing my response) she said, "Actually no, but continue." That odd change of mind made me suspicious that she really did remember, but then later said she didn't in order to avoid responsibility. Either way, I don't think the amount of pain she has caused me has ever registered in her mind. She's definitely lacking in the empathy department.

What I find hilarious--and slightly maddening--about this is that if I had done the same thing to her, she would probably be complaining about it non-stop (I have never brought it up around other friends, only the girl and my parents) and would have most likely filed a lawsuit against me. All this aside, she's graduating from college this May, so I won't have to be around her for much longer, thankfully.

I agree totally with Cyclelops and others here on this thread... unfriend this non-friend. If you have to work with this person, just withdraw personal sharing, and be as neutral and businesslike as possible.

It took considerable pressure to crush your toe...sustained pressure. To me this reveals a sadistic intent from this person who injured you. Don't give them any more chances to hurt you either physically or emotionally.

BTW... you might look this up: narcissistic personality disorder.
People lacking empathy typically also lack guilt and conscience.
This link may be helpful to understand difficult people, without all the big psychological terminology. Young people tend to retain some narcissistic traits until they mature, say into their early 20's. Past that if self centered behaviors, persist, they may be for life.

This is the best link I've ever read on the subject, and learning about it now, may save you much pain, in the personal realm and at work.

Don't worry, once she graduates in May, I'm going to greatly reduce my interactions with her. I tend to just ignore her nowadays. The only reason I'm still around her at times is that she is friends with most of my friends. She's dating my best friend as well, although he has been rather apathetic and unwilling to talk about what happened; I'm starting to not think of him as a friend either.

Thank you for the link, Mrs. D, I will check that site out later, for sure. Psychology is my major in college, so I'm already somewhat familiar with the traits and behaviors of a narcissist (and the girl in question fits them to a tee). I definitely won't let her get close enough to hurt me again.
