do you admit when you're wrong? Options

[Heathasm]

There are ceratain ways to do this, but first off
i think that people HATE to admit when they're wrong, most of the time, when they blow up at someone over nothing. even when they realise it was wrong and stupid they keep on defending their actions.

for example, the other day my friend was over and we were playing cards, she decides to leave all the sudden with her guy friend and rushes out the door, i said i was going to the bathroom and asked taryn if she wanted me to lock the door (because it was 2 AM in the morning). so, i lock it, goto the bathroom, come out and suddenly here this booming on the door. she comes busting in like a crazy person saying "FU** FU** FU**" and we though the guy had done something to her and she was like "no fu** you guys you locked me out fu** you". even after we told her what happened she was still like (after getting more calm) "well you were being mean to me all night blah blah blah you shouldnt of locked me out" -insert more excuses here-
it would of been over 30 mins sooner if she would have just come outright and said "sorry i missunderstood" jesus christ.

so, do you admit your wrong or make an even bigger ordeal out of it to try and convince the other person that you're right?
