I think that I noticed it for the first time two days ago, but it struck me once again, even more powerfully, today: the light is changing. I can tell that new seasons are sneaking in by the light. This is my favorite kind of light, though. There is a richness to it that you just don't get during the summer...or even the spring, when the light changes again. I guess that is why I love the spring and autumn so much. You don't get to see the light like this quite so much.
