Some women are just idiots.
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!!
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.
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.
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.
They dont want to sound shrill
