Somehow my sister has developed this annoying habit. Especially at funny movies. I refuse to go to the movies with her anymore cause she's turned into one of those laughers who laughs way too loud, way too long and then proceeds to talk...no NOT in a hushed voice, but her normal speaking voice...about every funny thing afterwards with her own witty observations. I want to tell her to please shut up cause I'm TRYING to watch the movie! She literally behaves like she was in her own home in terms of talking, getting up, and just making herself oh so comfortable. Last time she did this it got really quiet and you could feel the pissed chill in the air from everyone around us. I wanted to evaporate and die. So did the rest of the family that was along. She just has no awareness of herself in relation to other people.

Ditto on the cackling hens laughter. For all I know, women like that could be nuclear physicists, but to me they will always seem dumber than a bag of hammers.
