well if I'm looking at a guy I'm interested in or think is cute, I look directly at him not pass him! and when we make eye contact then I look away. so if you're not making eye contact with any of these girls that seem to be lookin in your direction then their probably just spaced out.
Yes. Keep in mind she could be spacing or thinking hard about something but I know I tend to look in my crushs direction so if he looks at me I'd know and then take it from there. That way I can watch him without looking like I am
could mean absolutely nothing, could mean she's checking you out. your gonna have to make a judgement call. maybe go up to her and ask her name? ask if she knows yours? if you've never talked and she knows your name, maybe she knows a little about you and is interested.
