Well, generally speaking I have sensory over-excitability when I walk into new environments - especially if people are staring at me from multiple angles. I've gotten slightly better though. In high school, it was horrible when I was late for class and I'd get a vicious stare from my teacher combined with the class' silence as I made my way from doorway to seat. As a result, I used to bang into a lot of things along the way. But once I'm comfortable and my external sense-stimuli has calmed down, I can just sit there in tune with my intellect and own any shallow sensor in a debate. But until then the sensors have the upper hand.
I'd like to return to this idea of over-excitability for the first few minutes in a new environment because I want viewers on here to understand how bad it is some times. Imagine all your pet peaves combined are occuring in front of you while you also are compelled to be on your best behavior. This contradiction and tension is the best I can explain what the first few minutes are like as I'm adapting to a new environment.
