Yeah, hi. You don't know me, but just hear me out.
I know who and what you're talking about. And I've been in a similar situation with the same person.
How you reacted to your own tragedy doesn't make you a bad person. Thing is, while I'm the first to admit Karissa is one of the most annoying people I've ever met, you were still kind of a douche to her.
Again, not judging at all. I'm technically the person who first treated her that way to begin with. I'm just making sure you understand where the anger's coming from.
