When strangers stare at you it means one of two things. Either you are wearing something really weird like a top hat with ostrich feathers. Or they are marveling at how pretty you are which is one of the signs someone thinks you’re attractive. The more symmetrical a face, the more attractive you are. So, if you are out in public and happen to find a lot of eyes on you, you can rest assured of this being a sign a stranger finds you attractive (or many strangers, for that matter).
