Have you ever met and had chance to talk to someone "famous"? Maybe an actor, politician, musician?
If you have were they different from their public persona? Were you pleasantly surprised or did you find them obnoxious?
I've bumped into a few "celebrities" (not a nice word these days) over the years, mainly in West London pubs. They've generally been ok people who are happy to chat. Friendliest and nicest ones I've met have been Bill Beaumont the former England Rugby captain, Norman Wisdom, Eric Clapton and Micky Dolenz from the Monkees. The latter was a really great guy. Russell Crowe seemed alright but he'd unsucessfully tried to drink the pub dry.
