This conversation happened just as I stepped into a different room for a few minutes, leaving the birds with the Boy but still within earshot.
The Boy (to Piper who was calling for me): "It's ok, she's not gone. She's in another tree"
Me: "Did you just tell him that I was in another tree?!?"
The Boy: "Well yes - that's the way Piper sees it!"
Some days I wonder who's the biggest bird-converted person in this household...
