Ron stepped forward and put his hand to her waist, and then carefully lifted her left hand. He was close to her, and could smell her perfume, at least he thought it was her perfume. The music came on and he didn't recognize it, but he assumed that Luna had put on something steady and easy for dancing.
He tried to relax and nodded his head to music, "So do you do much dancing these days? What do you do with your time?"
He was trying to make some small talk, but his mind was on those memories of dancing at the Yule Ball. His horrible robes, and his inability to dance kept coming back to him. He wasn't very chatty when he was distracted, and now was no different.
