When in doubt laugh it out... Or not?

When having a serious argument with a friend, I began to laugh because of all the dumb things that was coming out his mouth. It was a hard transition to be serious and argumentative, because I had to catch myself and stop laughing. After that incident, I realized I tend to laugh during serious situations (only some). That is because I am so attentive to the conversation, I will see that nose hair coming out...

Laughing at someone who is extremely frustrated or angry at you is a good way to say "I don't give a damn!" Some say it's teenage "superiority laughter" which is laughing at the person because teenagers feel more uppity than their peers. And I definitely felt like I had won the argument because I just laughed at their irrational anger towards me. Although, I wouldn't say I felt superior...

Another theory for laughing is using it as defense mechanism. I'll laugh when my parents are lecturing me.... Cause I didn't do anything bad. Just stayed out real late. So I'll laugh at their viewpoint because my viewpoint is that I didn't do anything wrong and they're tripping about nothing. 

What I did last night:

Went to this thing last night. Definitely not going back to City Nights. Too much there (noisy drunk people and harassment) 

Parents picked us up cause we couldn't catch Bart. I was a little bit laughing when they were lecturing me, but then I got guilt tripped.

Well laughing is a good mechanism because for a while... I can trick myself in thinking I'm okay, but in reality I'm still affected by what my parents are saying.
