LW1,  I just hate when people don't think clearly. So he didn't "hit on her" at the reunion because he thought it would make the other classmates uncomfortable?  W T F  ?  First of all, what makes this ding-a-ling think the other classmates would find out he was hitting on her? He could have done this in the hallway outside the dance room. He could have done it in a dim corner of the dance room or while serving her punch at the food table while everyone else was busy chatting or dancing. He's a rather dim bulb. She won't lose out much if he never contacts her.
