no I don't. I live in the Dominican Republic, and am Dominican-American, but I don't speak Spanish, though I can read and understand it well enough to get around and live. Probably because none of my friends speak Spanish and I work online, so I just converse in English.
My father and brother both teach English professionally, and my parents suggested I get a certificate to do it too. If I do, all the adults in my family will have worked as teachers XD. But I'm not really interested in teaching English. I'm applying to work as a writing teacher.
