Was riding in a construction zone so no one was around to laugh or pick up the pieces, depending on how you look at it. Was trying to pop the top on my water bottle with one hand when I looked up to see a stop sign. I instinctively started to stop, the water bottle started to slip, I accidently squeezed too hard on the front brake and presto - unexpected dismount!
All I can say is I landed on my feet, whacked my shin on a pedal, and thanked myself for buying a women's model bike with the top tube parallel to the down tube. It happened so fast I barely had time to think - oh *$^&@#!
No pain, just embarrassment at my clumsiness/inattentiveness. All's well that ends well.
(Yes, I always wear a helmet and gloves.)
