I am certain or truly believe that I had my lucky ring in my pocket when I walked across the bridge. But my sister says she is certain or has no doubt that she saw it in my hand, and that I dropped it when I reached for my phone. It is strange to be so certain or sure about something and then find out that you are wrong. All I know is now I am certain or really believe that I will never see that ring again, so I hope that it brings someone else some better luck!
