I am having a bad day. Went out to shop, but my knees and legs were not cooperating. Did what I had to do, sat in a nearby park for a bit and actually nodded off (not smart for an old guy in this city these days). Started to make it home, which proved very difficult — specifically, painful. As luck would have it, a friend drove by, stopped, helped me into his car, and drove me home. It may be the weather. I have been lying down for a couple of hours now and my legs are still killing me. In short, minimal blogging today.
