One of the first thing you'll notice about Kyle is how unnoticeable he is, and that he very much prefers it that way. He's always had what could be loosely called a talent for entering or exiting a room without others noticing. He's the kind person that will be almost directly behind you when you ask where he is. It's not with ill intent or impish pride that he does this, most of the time, it's just how things work. He's an observer more than a participant. He'll usually know more about you than you know about him, although he may call you by the wrong name. Due to his going unnoticed, he usually hears more than you think he does, and definitely more than he cares to.
His clothing these days is made of any combination of shirts from different colleges, a well-worn jacket, work clothes, and a button-up (if it's Sunday). He would 'dress to impress' if 'cords I can afford' didn't override that desire almost all of the time. He enjoys fall more than any other season, though, as he works better with layers.
He hates talking about himself. If he ever had to stand in front of a crowd and explain himself, or heaven forbid he have to put it into writing on the internet (the most permanent of permanents), he would absolutely hate every second of it.
For the most part, he can be accurately described by one of his most commonly said phrases:
"Don't worry about it."
