I try to make people look like a fool of themselves by persisting of an intellectual discussion with them and still remaining professional/kind.
All but very few gives so if that doesn't work I then of course leave them to be. I don't intentionally out of my ways to "make" someone feels bad, do harm, etc.
Depends on what the outcome is and what the subject is about then I might correct them if it's simple and whatnot, but then again other times I walked away.
I don't believe in revenge. To me, it lowers me down to their level. Makes me no better than they are. I won't lose my humanity to 'get even'. But I also don't walk away too easily. It's a hard decision I make. I don't let it go until I go round in my mind of what happened, why it happened, & HOW to prevent it happening again.
I'm more of a passive person. If I don't let something go it's only for a short while and I'm not the revenge type. It's rare to see that type of behavior out of me.
