I get this a lot. I have a Masters and several minors in nothing but Liberal Arts. But I work in CS at a fairly high level. It just blows people mind who have a hard time seeing how they can possibly ever relate to one another. To me they're all the same. I'm drawn and willing to learn whatever that interests me. If anything, I've always felt that I can learn CS on my own (which I did) but I wouldn't be able to learn Liberal Arts stuff if I wasn't exposed to it in a classroom environment.
