Depends if I had it coming to me or not.
She was a collections agency manager. Those people are the epitome of evil. I think this might be what we call "karma".
Honestly, haha I felt bad for her until I read she was a collections agency manager.
Damn, I'm mean
Ah well... but to answer the question: depends if the person is truly remorseful for what they did.
If someone does something royally fucked up to me and thinks they can get away with it, then no, I don't forgive. In fact, I take the extra step to get revenge. Might sound mean, but hey, it works.
Some people have done screwed up things to me that they should've been remorseful for. They weren't, but when they saw what I could do back, they kinda realized they could've taken the easier route. Lesson learned for them.
