The E's each have a stick with feathers at the end. Every night while I'm sleeping Eddie brings them upstairs and lays them on the floor beside my bed. Sometimes the sticks are crossed, or side by side, or even with a distance between them.

Every day I take them back downstairs and put them in a different location, different room.

Doesn't matter. They will reappear during the night!
