I rode my bike about 5 miles this evening, after being on my feet at work all day. When I got home I was really tired, but I felt really good, too. There was a warm breeze, and I could smell flowers and grass and sunshine. I lay down in the driveway to stretch, and watched the tree branches sway and the shadows dance all around, and I felt happy. For a little while, I was just happy, and nothing else.
