Imaginary Friend?

This evening in the bathtub Charlie looked up and complained, "Mommy, Louis hit me. Louis hit me in the tubby." He gave me a pouty look.

Confused, I asked "Who's Louis...?" He has, after all, named a few of his toys -- Julian the lemur after the lemur in Madagascar, and a tiger unfortunately named Teeth.

Charlie pointed to the air next to him. "He's right there."

"Where?" I asked again, still thinking maybe I was missing something obvious.

Charlie waved in the same general direction again. "Right there."

"Oh," I said, deciding to play along. "Louis, you need a time out for hitting Charlie."

Charlie nodded approvingly, apparently satisfied with the punishment handed out to his imaginary friend. Hopefully they will play nicely in the future.
