We see the silhouettes of our loved ones at the change of the day. The time when the sun is low and day is becoming dawn. It is a time when we are always late and a time when we have had neither enough breakfast or enough Doggie book.
The silhouette is outlined by the windows - by the changing light. It is the pensive pose when we pause between leaving or returning. It is the small moments when we collect our thoughts to accept the change that awaits us.
It is the time when we are going to day care or to work. When we are taking our positions on the treadmill and are none the better as human beings for doing so. It is the time when are doing what must do, not what we would rather do.
The silhouette is the image of the person that we think of when we think of a person as themself, and just themself. They are not looking at us or concerned with us. They are on the cusp of some change - as are we - and it is their silhouette that commits their image to our memory just before they change.
