So true! Everyone who crossfits wants to talk about it. That's why people like to call it a cult. The day I had my first CrossFit session scheduled back in May, I was talking to a guy at work about it. This other guy overheard our conversation and came running over to gush, "You're going to CrossFit??? I CrossFit! Which box are you going to? You're going to LOOOOOVE it!"
I think people are just so happy with the results and the experience that they just want to share it with everyone. I can see how you might get tired of hearing about it if you are not crossfitting though.
