Lying on the floor in their room, the boys clamber raucously around me, exhausted, my back aching...I look up and see the dust motes and think, "How lovely," then "I really need to clean those curtains". Seized by sudden energy, I pull them down, take the screen out of the window, hop out onto the patio and shake them out furiously. Back into the room, boys looking on, up go the curtains, refreshed and ready to block the light out on their next nap. Feeling quite satisfied. It was the highlight of my day.
