If the person is just staring at you and when you make eye contact with them, then that person likes you. If they keep staring at you, it means they want something. If they're glaring at you, they're mad at you.
He might like you if he flirts with you and gets mad if you seem to be getting too close to another person. Or if he's shy, you may catch him staring at you, and then looking away quickly, blushing.
It sounds like they have a crush or they were just looking at you. If they do it a lot, they probably like you. Try talking to them a little more, and be a judge as to whether they are into you.
i think someone has a crush
It most likely means he likes you but doesn't want you to know so he looks away and acts like he was never staring in the first place.
if he/she stutters when they talk to you
When your friends tell you that your crush is always staring at you, it could mean that your crush is interested in you or finds you attractive. Nonverbal cues such as prolonged eye contact can indicate romantic interest or curiosity. However, it is important to consider other factors and not jump to conclusions based solely on this observation, as interpretation of body language can vary depending on the individual and context.
It's possible he's feeling shy or unsure about how to approach you. His behavior of staring and looking away could indicate that he's interested in you but may not know how to act on it. It might be worth trying to strike up a conversation with him to see how he responds.
He has a crush on you. Next move is yours.
if course he likes you!! unless he was looking at another girl... but i doubt it looks like you got yourself a crush!
i think you should tell her and there is three ways1-you should catch her staring at you.2-see if she blushes around you .3- See if she giggles a lot around you (important).
stare at you, be more caring with you than they are with other people, if their shy they might quickly look away when you look at them(this means he was staring at you), their close friend might be nicer to you then he used to be..idk...
he keeps staring at you that's how you know:P
