You must be very very good looking ;) I think I have the Answer you are looking for !! Ignore the other droids !! These are not the droids you are looking for..... Lol :) I like that I can amuse my self :)
Why do guys check me out so obviously?
You are learning firsthand about boys and that boys are NOT the smartest animals on earth so they usually do things beyond explanation sometimes. So expect boys not to use common sense to be kinda secretive checking someone out. Boys grow into men and some never change unfortunately, but just don't expect much from the male gender of our species
You're probably very pretty.
They are more tunnel visioned than women. However, women instinctively check men out too but it is subtle as women have better arc of peripheral vision.
Ignore them, just be proud of your looks and don't it get to you.
