most likely because You are so fantabulously HOT! BUT the ego-maniac stench is coming way too strong for their liking. Who wants to get caught staring at a good looking jerk? . . . that would just make him feel better about himself. Girls have this "player" radar lol it works great
Um..are you sure you're amazing looking? Have other people told you that you're amazing looking or is that just your opinion? It could be either 2 reasons:
the girl looking at you is shy and she looks away because she's too shy to make eye contact
or you are staring at the girl, she notices you staring and looks away so you won't make eye contact and then start talking to her
If you never smile, this could make a girl that was interested in you not engage you. Maybe she would have approached you, but not too many girls are gonna approach a guy that is ice grilling and not even smiling.
maybe if you are that amazing looking then its because they are nervous that you will judge them or that you won't think they are pretty or whatever. maybe you would get a better reaction if you went up and talked to one of them, maybe asking a made up question like "where is the closest place to grab some food?" or "do you know where ... building is?" even if you know the answers.
if you are intending to let them know they are looking and always catching them looking at you. so sure they will look away and treat you as you are not there so you wouldn't think more high of yourself as you seem to be.
umm, I have to tell you that everyone has different tastes, and different preferences...so even if ALL the girls are looking at you that never mean they are all impressed by the way you look ...maybe they just feel how high you think of yourself which definitely is getting on their nerves.
