This happened today in the morning. I wanted to buy a new double purpose bike, a 798 cc. Yesterday I headed down to my local BMW dealership and fell in love with this one bike. So the sales person offers me a demo ride. I returned this morning with my friend, who has being the person who got me started and excited on the idea.   I hadn't ride a bike in ages, over 30 years, but I thought that it would be just a matter of just getting used to it again. Long story short, as I was getting acquainted with this one new demo bike, I started to slowly ride, but decided to stop again and put my left leg down. I immediately felt a sharp pain in my left hamstring and lost strength, so I just let the bike drop to the ground. Needless to say the salesguy, his partner and my friend saw everything and rushed to help me, I tried to get up, but I had pulled my hamstring bad. They all looked scared, worried and appalled. I was so embarrassed. I tried to climb up again, but my leg just wouldn't let me. I limped back to the dealership's office and told them I was so sorry. I immediately started filling up all the papers though. I'm getting my bike anyway. The bike suffered very slight damage. I guess I took the worst out of this. I'm sure they didn't' say anything else, other than asking me if I was ok more than once, only because I was purchasing the new bike.
