One pernicious observation from leveling up is people with a dicey sense of respect for others flip out when you assert the same boundaries that they do.

An example is an acquaintance who expects you to put up with some poor treatment that you're pushing back on. Upon experiencing the light version of it in their own life, they dramatize that the sky is falling. 🙃 Is it? Why wasn't it falling before? Terrible things only suck when they happen to them? 🤡

Watch out for the same people calling you entitled. You aren't, they're projecting.

A great way to shut this down is to use exactly the same language on them that they did during your situation. (A better way is to get them out of your life but sometimes these things take time).
