How can you know that some one like you???

Its hard to know if a person likes you because sometimes its just a person's natural way of dealing with other people. So its hard to know because sometimes you're expecting that a person likes you though he/she's really not. But I can say that a person likes you by the way he/she stares at you. If you feel that there is something in the way that he/she looks at you, then try to confirm it by being close to him. Another is when a guy/girl cannot look at you eye to eye because he/she is shy. Another again is when a person always finds a way to be near you, to see you and to be close to you then I think he/she has an intention. :) Well, that's just based on my experience and what I see. :)

Eye contact is a sign of attraction but sometimes it can be very deceiving. Just be sensitive and you'll get all the signs you need.
