I'd like to make a note on the previous post. You are allowed to feel awkward if, as the greeting is coming to a close, an adolescent comes up behind you, taps you on the shoulder, and says 'HI' as he walks past. That's not how these greeting times are supposed to go. That is strange behavior, and probably indicates a Condition that you are not responsible for. Move on.
