Elder son with his laptop game, brokering a deal for bananas with Saladin (he says) and half listening to a video episode of "Yes, Minister," while the younger two, elsewhere in the room, read their books and put off going to bed for as long as possible. (ink and watersoluble pencil)
Those moments when children try to suspend the necessity of going off to bed can be the most harmonious and pleasant of the day.
The expression of concentration is perfect. Love the composition and colors.
