It does, indeed, depend on the situation. We talking someone bumping into you, to being cheated on levels of difference, after all. I'm very laid back for the most part, but then, I had a hard betrayal about half way through last year, and I'm still struggling to get over it. I'm finally starting to process it properly here lately, and though I won't "forgive" until I get an apology, I'm done holding a grudge.
