Yes it is a topic of much debate on another board. I read that board occassionally and as someone mentioned there is a group that thinks they run the board, and heaven forbid anyone disagree with their opinions. I didn't see the one about socks. I will have to take a look when I have time.
Many men loose the jackets after dinner. My husband has changed from the tux to dockers and a knit short once or twice. If I were not comfortable I would change also.
Hope you have a wonderful cruise.
