You think you see someone famous. You pass on a fleeting chance for an autograph because you're afraid, embarassed or otherwise discouraged. Now you are haunted by the specter of a missed opportunity.

In my case it was watching John Wayne get on board a passenger plane with me from the U.S Virgin Islands to the U.S. My wife at the time talked me out of asking for an autograph. She and I are no longer married but John Wayne is no longer signing.

What's your story?
