I don't think I've ever had an annoying coworker. I've had coworkers who I thought were annoying here and there, but it was never their defining characteristic. There is only one conclusion that can be drawn from this: I was the most annoying person in the office.
I should have seen this coming. What with my entire personality and everything that comes with it. I suppose I should apologize for that, but I won't, which is one of the countless reasons I was the most annoying person in the office.
Fortunately, I work at home most days now, so I've got no one to annoy but myself, which I do.
