Do I Need To Know Why?

I really have a thing about celebraties and always wanted to be one. I've seen a fair number in my life, but not a lot. Today I was meeting with my ESL client at a local Starbucks where we talk for two hours a couple times a week. As we were leaving he told me that there was an actor sitting at a table outside. I looked over and saw an older, not too well put together guy and said that I didn't think that was anyone familiar. And then I took a second look and realized that it was Mel Gibson! No, I didn't acknowledge him at all, nor did anyone at that moment. I wonder if he cares either way. And, I wonder why he was sitting in a Starbucks in Scottsdale drinking coffee.
