I'm going on what Koreans call MT (short for "Membership Training"). I suppose Americans would call it a retreat.
I was invited by the swing dance group I've been taking lessons with for the last month.
It has been described to me as a weekend of drinking, dancing, drinking games, then I, suppose, drunken dancing...
The following weekend I'll be celebrating my birthday. The weekend after that I'll be going on a retreat. Then right after that I may be going to China for a week or so.
