I learned (sort of) how to play Mah Jong (Mandarin for Jewish women chatting and playing with tiles). Turns out Mah Jong has nothing to do with the solitaire matching game one finds on computers and everything to do with complicated rules.
I did not master the hands. (Apparently, you’re not supposed to say things like “Oooh, I really like the dragons!”)
I did figure out the names of the tiles. None are named George.
My lesson did not include scoring (although I was told that people generally play for money).
