Ian,
I have no time for drunks, chin strokers, the soul-less, the spaced out, record dealers, DJs, promoters and most of the other types that fall by definition into the 'can't dance, wont dance' collective.
I have sympathy (read encouragement) for people with a confidence problem. I was once one.
Of course there is nothing wrong with dancing at home! There's also nothing wrong with getting a bit of help & moving on with your life.
Col.
