So, I really liked French in college (3 years!) and taught myself Esperanto, and thought, "I know! I love languages... I'll get a minor in linguistics!"
Yeah, no. I discovered pretty quickly that linguistics has nothing to do with learning to speak a bunch of languages, and was just endless sentance diagramming and instructors who are fascinated by glottal stops.
So I went and lived in Germany for a couple of years and learned to speak that, and then had to stop the fun and start a career. Now, I have forgotten all of my French and most of my German, and my Esperanto is crap, too, and so I'm back down to measly English.
