Guys With Yarmulkes Dancing With Girls

I’m at the JConnectLA party tonight. About a quarter of the crowd is nominally Orthodox. Many of them dance with the opposite sex. Many of them are my friends. I watch them swaying with their yarmulkes and I notice that they tend to dance the same way they daven. Those who are stiff in shul are stiff on the dance floor and those with weird extraneous movements in davening have the same movements while dancing.
