If you're truly in a band and you guys have been together for a long time, there's a family bond that you have. In fact, I've talked about this with therapists, especially if you're talking about a relationship, because when you're with somebody, you're going to your family, and she's alone.
I find myself going to places where I really have no business, speaking to these people in a whole other field that I have no extensive knowledge of. But I do it very often because it scares me.
