1. knees will be pointed towards to the person he is attracted to often will make eye contact but quickly look away (if this happens very often then its a sign he likes her) slight leaning towards the person less obvious are physical symptoms, when speaking with someone a guy likes his pupils will sometimes enlarge and the blood flow to the skin will increase (most easaly seen in the hands and face)
2. Guys might look at you shyly, then look away just as girls do. In other cases they might pick on the girl they like. It all depends on the guy.
