So, I often act casually as I try to prove that I am indeed smart or skilled with this or that thing. In doing so, I frequently make mistakes that wouldn't have happened if I had not tried so hard to look casual.
Therefore, I trip on the words I speak as I explain something complex or I tip over lamps while trying to accomplish daring dance feats or I cruise over curbs while taking sharp corners in a residential street.
Sometimes my brain is a paranoid robot of insecurity that spins into an electric cyclone of dismayed gears. But most times it's not. I like those times the best.
