Agree on CrossFit. At my last job, there was a group of people who went together and would talk about it. For hours, every day. Got really sick of hearing about it. My wife even joined up for a while. While she had fun and it was good for her, I just didn’t have the patience to listen to her talk about it and all the gym gossip when she got home. I felt guilty knowing I should be more supportive, but I just couldn’t do it after hearing about WODs all day.
