It is October. A cool morning that settled into a pleasantly warm Saturday afternoon, the way an October Saturday does in San Diego. Around the house, the Halloween decorations have begun going up, and the kids are excited. They have only recently finished being excited about a birthday, and soon they will be excited about Christmas. Every season has its presents or candies to look forward to. Sometimes both.

By this time she is three, but on the wall she is still a baby, and her brother is barely done being a toddler.

There above the dining table she is still a baby today, younger than her baby sister. And—for now—she is the same age as the brother that smiles above the spot where she used to eat her cereal. The brother that eats his cereal in the living room these days is, of course, still her senior.

If the shift in tense is confusing, just stop and consider the layers of "now" that are in that kitchen. An October afternoon. A morning in May. An April weekday as I write this. Whenever it is that you read it. Photography is weird.
