freud thought it important enough to write about - Jokes and their relation to the unconscious. Humor is a subject that has been under-researched because people didn't take it seriously! That is changing now.
Personally, we only ever watched comedy shows together as a family. so it's something that was reinforced for me. my cousin grew up watching Bonanza with her dad. We NEVER watched Bonanza!
ETA - I thought your posts yesterday were HILARIOUS!!!
ETAF - I definitely use humor as a defense? and when I am aware of it, I will try to say something about it in the post. like zoo's recent stuff about her prev T, there was a lot of conflict there that I could REALLY identify with - if your T is a flake, does it negate all your work? Because that was what my June '11 rupture was about, and what brought me to PC. I was like, who IS this guy??? What's WRONG with him??? SOaFB!!! (pardon my french!) and then that brought out the fart jokes... I'm not proud...
