Skinned Knee

I skinned my knee! Can you hear me whining? LOL I learned a valuable lesson yesterday while substitute teaching Gym class. Guess what it is? I am too old, and too fat, and too out of shape to be playing sports with a group of 8th grade kids. That's the lesson I learned. I didn't pick me feet up while running and I stubbed the toe of my shoe and down I went. I guess I shuffle when I walk, because that's the only explanation I can come up with for why I took a tumble. :(
