What are three things that would definitely trigger your anger?

First and foremost it would be someone disrespecting and/or harming my wife in any way. Followed by someone disrespecting or attacking me in any way, and someone intruding uninvited where they do not belong verbally or physically (especially if they are asked to butt out or leave and they refuse to do so).

If I didn’t trust someone with my money or other belongings I wouldn’t want to associate with them. And it wouldn’t have anything to do with whether or not I liked them.

wild, crazy, sex escapades. nobody better try that on me.

people twisting my words
questioning my integrity
and when they think I cannot sense their condescension because I speak another language

Animal abuse is the only thing that really “triggers” me

Littering, racism, animal cruelty
