After posting my summary of our holiday, I found this by James Lileks. He expresses it much better than I do.

” I hated to let the day go. It’ll never be like this again. It might be similar; it might be better; it might just be different and interesting in a way I can’t predict. But everything that mattered was here for a while, in some fashion, and everything felt normal. It was a cloudy dank Saturday, but the weather didn’t matter. Nothing felt like goodbye. Everything felt like Hello.”
