My most disorienting experience was when I was away on business and dropped
in on the local SCD group (as you do..). With the exception of the group
leader, the entire contingent was female. The next dance was announced and I
turned to the lady next to me and asked her to dance. I was met with a
complete refusal - this lady always danced as a man. Since I knew the dance
well I was very tempted to offer to dance it as a lady but thought that
might cause more confusion than was justified in the circumstances. And
after all there were plenty of other ladies to choose from.
