How do you tell someone you like them without saying it?

usually ur eyes can tell it all. lol like if u dnt wnt to say yo bayb i love u then look at him or her in the eyes in a very loving way. that usually gets em haha:p i would no. but if u dnt think that will work then try to give out somthing different in the way u tlk or kiss. i dunno i think the first ones better
