Yesterday, I called the grandparents'.
S2 (our 3-year old) picked up.
"Hello, S-", I said, "how are you doing?"
"Appa!," she squealed. Then paused.
"What is your name?"
"It's Appa, you silly goose," I said.
"What is your name?," she asked again.
Then Mom got on the line and explained that grandpa had lectured the kids on always asking who it was on the phone. Hence, "Appa!" followed by "What is your name?"
