Day off and running with it.

Today was my day off. I began with a nice run, about 5½ miles. It was early enough so the air was cool. About half way home, I noticed a car pull over to the side of the road with a flat tire. Wanting to help, I stopped and asked the lady if she needed some help. She didn't know how to change a tire so she was more than relieved with a helping hand. I have had some skill with changing a tire, it's not like it's hard, or so I thought. After I jacked the car up, I preceded to loosen the bolts. That is when I ran into some difficulty. The bolts were on so tight that even with both the lady and me pulling on the wrench, it wouldn't budge. I tried one last effort and heard a pop in my shoulder, I hope that's not serious, I thought. I gave up when she told me she would call one of her relatives to help, they have power wrench. She was thankful that I had stopped. I am hoping that I didn't hurt myself. The marathon is coming soon.
