Heard Kyle cry out. Went to his bedroom to fetch him.
When I went to pick him up, he said wait, I need. . . (as is usual for him going anywhere--even room to room--he needed to pick some toys/cars) after a pause as he looked at the little line of cars in the dark on his bed, he turned back to me with his arms up. "Just me."
He then joined Robin and I for the rest of the night. :-)
