Impatient

I called a patient to confirm an appointment with the doctor I work for, and her husband answered.
"Hello, may I speak with Anna?" I asked.
"Who?" he said.
"Annna."
"Santa?"
"No, Anna."
"Who is this?"
"This is the doctor's office calling for Anna."
"Who?"
"The doctor's office calling to speak with Anna!"
"Oh, Anna," he said. "You'd better talk to me; Anna is hard of hearing."
