That I will admit to to the entire planet via the internet? As a kid I wanted to see what it would be like to swap hands on the handlebars. Promptly face planted in front of 20 or so neighbors. Several adult men came over to see if I was ok. Minor road rash and great embarrasssment.

There are a couple of stories I will only tell to someone with middle stage Alzheimers when we are alone. Enough attention span to listen to the story and no ability to remember it.
