Man, don't worry about it. At least you were by yourself. This past summer, I was at the Honda Hoot (yes even on a Kaw) and went to Deal's Gap to ride the Dragon. I had made a couple runs and went back to the overlook where tailofthedragon.com had their tent set up. There were probably around 40 other bikers around and the guy from that website came over and took a picture of me with my bike to post on their site, then we talked for a little while. About 20 minutes later, I walk across the road to get some pictures of the mountains and I hear this CRASH!! I turned around and looked and my baby was on her side with this old dude and his wife on a Goldwing backing up near my bike. I run over yank it back up and all the guy keeps saying is "I didn't touch it, I didn't touch it"! I couldn't prove he did it and no one else saw it either but he heard it from me just in case. In all honesty, he probably didn't do it, the bike was on an incline and I think it just fell over, even though I had been there for almost 30 minutes. It fell on the left side, broke the mirror, bent the clutch lever, scratched the fairing bad, and broke the rear set bracket which made the hour long trip back to my hotel interesting to say the least.
It happens to the best of us. Take care
