Fall has fallen. It is cool, and I'm wearing jeans for the first time in months. OK, they're lightweight pull-ons. But it is the first time in months I've felt the need to cover my knees. Just beautiful. A part of me is happy to see the end of a weird spring/summer, but a part of me is not looking forward to winter. I have a knee and ankle that are vaguely aching. What's that all about? Old age? Coming to get me?
