OhOh! Check out what I found in a
v.helpful website powered by Wiki.

1.If your crush smiles a lot and says huh when you are talking, he or she is probably crushing on you! so don't worry!
2.If she/he doesn't seem to want to talk to you, she/he either doesn't like you or is shy around you. Be sure which one it is before continuing. Most likely it is shyness, unless you really stink, or a real jerk. Watch your hygiene.(Reminds me of someone.)
3.Sometimes, asking a friend to tell your crush something is a bad idea, because it may be taken the wrong way. Don't get your friends to do/say anything for you. Do it yourself.
4.Make sure that when you talk your voice isn't shaky and that you feel perfectly calm.

Some of the tips I hand-picked out! Enjoy!
