Fear- consider it conquered

I finally conquered my fear. I am meeting 1 on 1 with my biology teacher- eek! He is so TALL. No laughing allowed, I am so intimidated by this man. But alas, I have set up an appointment with him for the sole purpose of trying to understand the more-scientific-than-it-sounds concept of DNA slippage. 1 irrational fear down, approximately 3 to go (drowning, hand injuries, and styrofoam). The no laughing rule still applies here- you're all just as big of freaks as I am, admit it!!
