.....it depends i guess
if its something im sorry about doing, ill apologize. ill usually leave the person alone till they calm down, then talk to them about it maturely when they are calm. im not about to be screaming and arguing, too old for that. a lot of times when people are angry theyre not trying to hear what you have to say, so its better to wait
if im not sorry thats their problem. if they got that much of a problem with that , knuck if you buck and we can chunk em or exit my life. though i have forgiven people who later came back and said they overreacted after i didnt apologize. and im not promoting violence or acting like a tough guy but if it goes there, im gonna defend myself. not apologizing just because someone threatens me with violence in an attempt to make me sorry
