What I did learn is how to play drums with my feet. I got a chance to tap my heels in and out of rythm for 1.5 hours every week. You try this at home and see what happens. I didn't. I prefer to say "Beluuuuuugah! Beluuuuuuugah! Ppppffffffbbbbttttt! Ppppffffffffbbbbttttt!" as many times in a row as necessary to either get sick of it or get kicked out, whichever comes first. Feel free to take guesses.
Well, besides the tapping, I have also acquired a pair of shoes which fit wonderfully compared to other shoes I've tried. They are classy and have a thin strap with LOTS of holes. I don't know why it didn't occur to me to look for shoes in dance stores until now.
I hoped that by the end of the class I could look and perform something like this

Perhaps, if I stick to it, one day there will be such a picture of me posted.
