If you like someone and wonder if they like you what should you do or say?

well you should talk to him and look for signs that he digs you, like he loves to talk to you he talks to you all the time........when you hang out with him he acts kinda nervous......and he trys to make you laugh........he is always sneeking looks at you......and other things so if you are realy pretty shure that he likes you then you should drop some hints that you feel the same way, LUCK :)
