I based this comic on a coworker. I noticed myself tensing up and being defensive whenever I had to interact with him. I looked around and saw that everybody else did the same thing, and as such, every person that coworker ever dealt with at work was tense and defensive. To him, it must have seemed like the whole world was tense and defensive.
I made an effort to be looser and more friendly the next time I talked to him. Not surprisingly, he made me regret it.
