Music teacher

It was a beautiful day, and little Ann woke up happily. She ran into the kitchen, singing a cheerful song. The cat was sleeping on the pantry, while a cockroach scurried across the floor.

As soon as Ann saw the cockroach, her lovely song turned into a series of panicked squeals. "Mum!" she cried.

Her mother came in, chuckled, and said, "Oh dear, you've found yourself a new music teacher!"
