Yeah, sometimes I wonder if I'm on another planet. However, TBH, it's often interesting to watch the various psychologies/personalities of the people involved.

I think there's a lot of similar comments about "dive bunnies", "mat bunnies", "mat monkies", etc., that I've heard in my life. Usually mentioned over a few beers and never meant with any real animus.
