It seems a fairly universal trait to see one's self as average. My skills, abilities, tastes, traits and sensibilities? They don't seem any too special or unique to me. I live with myself on a daily basis, and trust me, I have first hand knowledge that I'm really not that special.
What I forget is that I've lost perspective of me in relation to the rest of the world. The knowledge I've gained is indeed knowledge. My threshold of "normal", however, has increased, so I just don't notice. And gaining perspective from those around me is difficult. (Bird's of a feather and all....)
Recently, I had a good, refreshing, take stock of yourself sort of insight.

Okay, maybe not that epic.
I was looking at witty shirts
here, and saw this shirt.

My first thoughts were along the lines of, "Funny, but not hilarious."
And then I had the realization that were I to wear this shirt, the reaction of most people would not be "Ha!", but "Huh?"
My name is Lacie, and I am a nerd.
