Why do Muslim girls yearn to look older before their time?

I was a visitor in a medical clinic yesterday, where a young (adult) Muslim woman doctor was treating patients, here in middle-America. She did not "stink" nor did she look "out-of-date." She merely was dressed very conservatively in pants-suit and lab coat, and her head was covered by a lovely headscarf. I observed her to be competent, caring, and focused on her patients. "Fashion" didn't seem to be a concern to her. I don't know just where *you* are hanging, but I find your ertions to be both ridiculous and offensive.
