I hate the implication that any sort of interpersonal altercation needs to be dismissed out of hand as "drama"

Sometimes friends fuck up and cross lines. To such a degree that they cease being friends. I think that's why breakups and divorces exist lol

If it seems frivolous to you it's either because
1. It actually doesn't matter
2. It doesn't concern you or
3. You don't know what you're looking at or talking about
