I have only had limited contact with Bono. I don't like some of these things that I have heard about him in recent years, but out of the two times that I met him , I have one positive story to share.
Probably 15-20 years ago, I was working a camp with a number of big names. One of the featured clinicians was a product of the Bobby Douglas coaching tree. Bono, also a Douglas tree member, was working another camp 45 minutes away. Bono showed up at the camp I was working at to hang out with this other individual. Before you know it, Bono is grabbing a counselor and teaching technique on a mat to a group. He did an entire 2 hour technique session that he wasn't asked to do, and did not expect payment. He got a meal out of it and hung out with the staff and that was enough for him.
