John's smile doesn't waver--he's a little surprised a girl with her looks never learned to dance, but it's not unheard of.

He chuckles slightly, not unkind, but takes her hands as the song shifts to something a little more upbeat.

"They're doing more formal dancing, from the looks of it, but I only ever took one dance lesson myself so I wouldn't cripple my prom date in high school." he assures her. "Most of dancing's just moving the way the music makes you feel...and holding hands or holding onto each other can make it look more formal. Here..."

He doesn't stop her swaying, but makes a show of doing the same. He just adds a little bit of nodding his head, moving his shoulders, and stepping to the beat as his body moves back and forth--informal as hell, but all visibly in time with the rhythm of the song.

"See? Just relax into it. Move how you wanna."
