Not disbelieving- just teasing is all.

That, and a little wary. The only other person I knew that was that smart was a girl who was my first real friend, whom I watched slowly go from a normal (but supersmart) girl to someone with a dozen mental illnesses that have turned her into a completely different person. Where there was once endless conversation between us, there were only short shouting matches. Yaaay. Life sucks, neh? Then it comes back to restore your faith, before breaking you down again. 

I learn quickly too, I just don't care anymore. Not very many friends at all, not exactly in the most nurturing household and with the concept of faith out the window for me. Don't care enough to do something I know, much less learn something new. *shrug*
