I am feeling affection for this day. The sort of affection that is not nostalgia, because it is for the present moment instead of the past. An anticipation of nostalgia, rather--the sense that years from now, it will be a time such as this I remember with a twinge.
I think it is the rain falling quietly outside. Or the way the kids' playing spills through the house on the open weekend afternoon. I think maybe it is that Firefly wears Puppy's hand-me-downs I pulled out for the autumn, although I don't feel this tide of emotion every time she wears his old clothes.
Then I realize I dressed Firefly in the pants her brother wore the day he met her. The first time our family was together in one room.
