Name something you consider to be completely unforgivable, no matter what the circumstances. Why is it so egregious to you? What should happen to someone who does it?
I would probably say, if I were in a relationship - cheating, as I feel like it would knock my (already lack of) confidence and I wouldn't be able to trust that person again. In regards to friendship, I think being two faced and saying nasty things behind my back, but not having the guts to say it to my face.
