I went to a high school like Angus'. It was run by Jesuits, and the building was an old Masonic hall, so yeah, the whole secret society thing was right there...
Got a great education, though. And no, my parents were not wealthy, or even from old money, I was on scholarship. I was also the token non-catholic, so I got to run the lights in the auditorium during mass, and I got out of the Advanced Cathechism courses.
No dancing class in high school, though - it was all-boys. So I took dance in college. Actualy, it was called Stage Movement in the Theatre department. Monday and Wednesday was ballet, Tuesday was jazz, Thursday was tap, and Fridays - oh, Friday - was ballroom dancing. Viennese waltz (yes, it's different from a regular walz), Tango, Lindy, Foxtrot... it was a one credit course, and I think I took it four or five times.
And there is an advantage to being a good dancer. I slept with about half the girls in the class, and was propositioned by several of the guys, and it sure wasn't based on looks - I'm short and hairy...
"The best of times" doesn't even begin to describe it!
