So would you believe that sheerly by chance, I wound up on a flight a little while ago where a closet TG was a flight attendant? He was listening very closely and assured me after the flight that no one on the flight crew of about 4 had said anything derogatory about the cross dresser on board (me!).
I HAVE been curious what others might say when I can't hear, but it doesn't rise to the level of being concerned.
