Someone brought this up in another current thread: consider your end goal. What result do you want from an interaction, and how can you act in a way most likely to make that happen?

So often we react in an emotional way, and act like punishing someone else because they behaved inappropriately is the only just response. And i'm not saying you should ignore bad behavior or that no one should experience consequences for their actions. This advice is literally just to consider your options, to determine what course of action will most likely get what you desire rather than what feels good in the moment.
