I can do charm. Peope in certain circles have often commented on the way I lean on their mantlepiece at dinner parties. There is a technique of course like everything worth doing well. I tend to use the right elbow, leaving the left arm free with the cigarette and holder to languidly gesture when discussing breeding stock, crossed legs also add a touch of class.
I once tried the same when wearing a cravat at a dinner in Windsor, I was soundly horse whipped and banned from Berkshire for the whole season, it pays not to be too avant garde.
