When a guy gives you an smile is that an flirt?

Well, if your dad smiled at you, it was probably doting. If you're little brother smiled at you, he probably wanted a cookie. If it was a guy that was a few years older than you, than it would be creepy. But if it's a guy that's several years older, you should probably watch out. But I guess it would be considered flirting if it was put in the context of a flirtatious comment. he is either flirting with you or feeling sorry for you (showing pity). Boys will not do either of these things to people they do not like. A smile is a good thing. Just don't read too much into any body language. Nobody ever minded being asked a question. Unless he's a total jerk, in wich case there is no better way to find out than to ask him if he likes you. Ask him.
