Bow asks for his ball

This morning, Bow and Lawrence were outside in the outer pen, and Lawrence was reading to Bow about King David. Suddenly Bow went to the door, indicating he wanted to go inside. Lawrence went inside with him, and Bow took him straight to the glass and spelled: "I want to play with my ball."

"Do you want to play with your ball outside?" Lawrence asked.

"Yes," Bow spelled. "Outside."

Lawrence brought the brown basketball for Bow to play with outside. We're not sure what made Bow think of his ball just then. This is an unusual incident, because usually when Bow is outside he enjoys playing with what is there, and he never takes someone back in just to ask for another toy.
