If you really want to get someone to like you, maybe you could use a few of the tips given here.
Getting Them to Like You Back
Well, everyone likes a good-looking guy/girl. So work on your appearance and try to look good every time you see him/her or you're around him/her. Don't be a slob, dress up well and look neat.
Be humorous, witty when you talk, but don't overdo it. Humor is best appreciated when its appearances are few and far between, but racked with wit.
Smile because it brings out the beauty in you. Don't you think that a person looks best when they flash a (genuiane) smile?. A smile also shows that you're really enjoying their company. So smiling when that person is around serves a two-fold benefit: it brings out your true beauty and tells them that you're having a good time too.
And then again, you don't want to be too close or too open with someone. Some things are best left untold and seemingly mysterious. This makes the other person curious and gives them a desire to get to know you better.
Telling the person you like practically everything about you and sharing too many things with that person gets you in the 'friend-zone'. Which is fine if you want to get someone to like you as a friend. But if you want to go out with them, perhaps you ought to keep a few aspects of your personality under wraps!
As you can see, attracting someone you like isn't really a big deal. It is very easy as long as you hit the right chord with them!
