I secretly dislike really athletic people, especially the outdoorsy types. I think it's because they are often obsessed with a particular sport, and you end up hearing way more than you ever want to hear about it. Even worse is when they want you to go out and participate in the sport, too. These focused individuals have lost perspective and will subject the uninitiated to prolonged torture, such as "easy" bike rides, "short" hikes, etc. I don't mind being friends with athletic people, but I refuse to let a particular sport become a focus of what we talk about and do together.
