Mmm. ok. Well, why don’t you tell me a little bit more about what you would like? We have everything from mountain biking, to rock climbing to street luge.

And you've never done it before, you could say something along the lines of, " Oh, that's cool, I've always thought rock climbing was an interesting sport. Why do you like it so much? "
