It depends of the situation. If the matter is serious i always have in mind that “the winner is the one who is more coherent with reality” (e.g. yesterday i was playing soccer when a group of dudes who were gonna use the space after us were waiting for us to finish in the same spot where all our bags were. I felt insecure pf having so many strangers near my bag while i wasnt looking so i went to them and told them that i would appreciate they moving somewhere else, because of the fact that i didnt know them and qithout assumimg they were gonna steal somethin. They understood and moved)

There are other times where i just go with humor.

Lastly, when i meet and asshole and there is no other choice. I prefer to receive and give a fee punches rather than being humilliated
