I'm getting really good at it. I had secretly perfected a new technique, which I call the 'Dead Duck Float.'
I showed mum.
Mum said to stop being silly, but I know she was impressed.
When she went off to her ballet lesson, I overheard her telling her friend about me.
"That's my kid," I heard her say. "Always up to something. She'll be a great Quack Scientist some day."
Her friend looked over at us.
"The one on the rock?" he asked.
(That's how I know they were talking about me.)
I stood up and waved.
"Hi Mum!" I shouted.
"I thought you said they were practicing," said Mum's friend. "Not very obedient, is she?"
He looked disapproving.
I quickly stuck my head back in the water. I didn't want to embarrass my mum.
Silly old man. He's just jealous because all his kids turned out so ordinary.
