Some days, some series of days, will stay with you until all days leave. This weekend: the Potomac, muddy and swift from storms, and my son fishing on a rock with Lowell; Katherine insisting that we hike the Billy Goat trail in its entirety, because we might find turtles; DC on a cloudless evening; a piano recital at which Alex played Bach's Minuet in G; Katherine in a frilly dress; a breezy night on the patio; pizza, beer and wine with friends (Lowell, Mike, Myra) that only the arrival of 2 AM could end.
