Well, I have an immense fear of two things, I'll save the best for last though... ^_^;
I am greatly afraid of sharp things... when I was about 10, I had to go to the hospital for an appendix surgery, and I was very scared of all the sharp objects around me, and I couldn't sleep for 3 days. Ever since then, I've always been afraid of sharp objects. My hands always start shaking whenever i even see a knife...
Also (and this may seem funny to some people), I'm deathly afraid of the color pink. Yes, pink. There's an odd explanation behind it as well. Some of you may know I'm an extreme tomboy. Two christmasses ago, my aunt got me a pink thong. Yes, it freaked me out, too. Don't ask why she got me that, I have no idea. I have nightmares about pink... also, don't ask why.
Well, those are my greatest fears to date...
