Not sure hey - I teach in an elementary school in Korea. Female teachers always make a lot of the appearance of the boys - almost never about the girls. It's actually one of my pet peeves because I fear the boys one day being expected to fend for themselves, provide selflessly for their wives and families, it doesn't prepare them well if we focus on their appearances as much as they tend to do here. Mothers tend to do that a whole lot. As you said, some girls may have this expectation to look good, and boys carry a different expectation - we ask them to sacrifice their whole lives essentially, for society and family. Personally, it gives me a sense of meaning, and I have no complaints seeing my girls grow up under my wing.

One can only hypothesise if I had embraced the flattery I was given as a young boy, maybe I would have sought a different partner - maybe someone to take care of me in exchange for my wonderful look. It makes me chuckle to think of it - and I see your point - it is a little unfair in many ways because a person's potential could easily be stunted.
