I hosted a Medicinal Tea workshop. 10 ladies attended. We used fresh tea, dried looseleaf tea, and bagged tea, sampling many kinds and discussing the virtues of them.
I gave an impromptu class on Mosh History & Culture. Topics included various styles of music one would Mosh to, different moves and which genre they were appropriate for. We covered a lot of etiquette and safety. There was a small amount of history of punk and ska music.
The students asked a lot of questions and we had some practice of different moves.
