either he is completely in love with you and has no idea he is staring at you, or you have very beautiful eyes that put him in a trance. either way for you is good
Maybe its because she likes you or is trying to read yourexpression. But the girl might be trying to figure you out. If you don't talk to her, don't expect her to. It really does depend on the girl, but try to ask her. good luck! (she may be the judge-y type though)
he is trying to impress you if he does it all the time when your around. that doesnt necessairly mean he likes you but it is a possibility
It's difficult to determine the exact reason without more context. A blank expression could indicate surprise, confusion, or simply being lost in thought. It could also be that they were caught off guard or trying to read your facial expressions. If you're comfortable, consider asking them directly to clarify the situation.
It really depends on his facial expression. If he's smiling or looks at you in a "Edward Cullen" stare then he shows interest, if he's frowning or just staring at you then no.
Cats stare because they are trying to show their domonance over you. Plus, when they blink, they are saying "I love you".
It could indicate that he is interested in you or trying to connect with you on a deeper level. Eye contact can be a sign of attraction or intimacy.
It could mean he is trying not to stare at your eyes for too long to avoid being rude. It could mean he has some sort of attraction towards you.
His trying to socialise.
lol maybe he likes you or thinks your attractive ;) Say hi to him and see if how he responds; if he gets shy he likes you if he just says hi then leaves like he doesnt care, dont worry about it
It could mean he likes you, or he's trying to figure out what you're thinking (possibly he could like you and is trying to tell if you like him back!)
turn the light off
They keep trying to get your attention by you and stare at you when you walk by
