For men, the most terrifying aspect of a wedding is that the ceremony is followed by food often followed by dancing. Many men would rather rivet their thumbs to plywood with a nail gun rather than be dragged onto a dance floor.
We had precisely such a male in our circle recently, who happened to be doing double duty as the groom.
After expressing concern several times about making an idiot out of himself on the dance floor, a soon-to-be-sister-in-law of the groom jumped up and announced she could teach anyone to dance. This was a shock to those of us who know her because (a) she can’t dance and (b) she can’t dance.
