I believe that when you're in school, if one guy says a girl is pretty, all of a sudden the other guys will agree, it's like a chain effect. they all want to chase after one girl only because it becomes a competition thing. And plus, school ground is so much more compacted people see you everyday, they grow to like your face, or they know your personality etc. even if you weren't that attractive in the first place, people can see your inner beauty.
now that you are older, like when you go to clubs, they are all strangers to you. they know nothing about you and there are so much more girls around in the real world than just in high school. U're probably not ugly, it's just that the world and choices have expanded for you and everyone else.
