If you were going to take a class to learn one thing , what would it be?

I have been thinking, I have another year at being homemaker. I want to take a class one day a week I would like to get out of the house, and to have interaction with other adults. My husband said it is a good idea. I am thinking ceremics.I thought to myself, I’d probably make a whole bunch of ashtrays, or more nickknacks ,which I don’t need. I thought of , I’ll learn Spanish. I could be able to talk to my neighbor . What would you take?
