Immersion.

Walking home by myself after an extraordinary movie this evening, I realized once again that some days sink me so deeply into the sentences and images and sense of others that they leave me quiet and a little worn out. If I'm already tired because, say, I was up repeatedly in the night coughing, then I'm even less likely to want to reach out to put even more words together.

Which doesn't mean I don't have them. It just means that they want to be quiet for a little while.
