That's the full extent of my interest in you. Exposing your pettiness and hypocrisy, flicking you off me like a flea, and moving on without a second thought.
Not for nothing, home slice, but you don't exactly "flick [him off you] like a flea, and [move] on without a second thought." It's more of a "respond to every comment he makes with paragraphs outlining his initial wrong and lambasting him." In other words, "the full extent of [your] interest in [him]" seems to be to rise to every comment and barb he levies against you, taking the bait every time. You can say that Rex and pro and Doc are "obsessed with" you, but it's really just a case of you making a great target.
Just saying.
I'd say rex is obsessed with him. I'd also say that WB feeds the obsession by reacting exactly the way rex wants him to.
Doc, on the other hand, I really see nothing to indicate that he has much interest in WB one way or another, except to sometimes comment on WB's posts.
