How do you know if a guy feels comfortable around you?

Anonymous
Say a girl has known of a guy for a while but the two of them have never held a conversation--one that is more than a question and answer or greeting here and there--until recently. As they continue get to know one another, how would the girl know if the guy in this situation is comfortable being with/talking to her? Are there any key signs he would display?
