Dear Declan —
Yesterday, sitting on my lap as I took off my shoes after a long day of work, you said to me, “Daddy, sometimes during the day I miss you, and then I look at your shoes and I don’t miss you any more.”
What was extraordinary about this is that you said it as a statement of fact, reporting on your experience, without sentimentality. You had found a solution to a problem. This of course caused me, a grown up already on the sappy side before having kids, to be that much more overcome by the sweetness of your comment.
