What do you think about the type of people, men or women, that have the type of facial characteristics that?

make it look as though they have a permenant smile etched on their features?
i remember speaking to a secetary girl a while back, she had wire framed glasses, and she seemed to have this thin liped smile on her face the whole time, while she was talkin to me.
like she was in on some type of joke. like i ~no~somethin~you~dont no type smile.
but maybe this was the way she naturally looked all the time.
but it certainly was annoyin.
i felt like askin, ‘ what the f you smilin at’ ?
anyone else encountered this?
