You stand with the belligerent, the surly, and the badly behaved until bad behavior is recognized for the language it is: the vocabulary of the deeply wounded and of those whose burdens are more than they can bear. 

– Father Gregory Boyle

Empathy, the ability to understand and share the feelings of another gives you a superpower.

Taking the time to look at the root cause, the explanation for behavior is eye-opening.

What you may find is that their position is not one of hate or malicious intent but rather is one of woundedness.
