Oh that's just me pretending to laugh at their corny jokes.
Its the whole birds and bees thing,really...but I llike more natural laughter,bent over,rip-snorting belly laughter!!
You are right...some women have a high pitched giggle or do that open mouth guffaw...I've always thought that was goofy. I think that THEY think it makes them more attractive.
Some women are just idiots.
I get really self-conscious around guys. >_>
They probably think their laugh is embarassing so they change it up in fear of being unattractive. Personally I like a good silly laugh makes me laugh more.
They dont want to sound shrill
Subconscious way to flirt maybe
Because biology says men are attracted to higher pitch voices. It sounds more feminine. Personally, when a woman laughs at my jokes like that, I know she's faking it.
