The following is a genuine experience I had earlier this week. I was busy in the garden, minding my own business, when I heard a woman's voice, loud and clear, the other side of the hedge.
"Aren't they big and lovely?!" she said.
"Huge!" said a man's voice.
"It's because they're in a sunny position."
Ah. Now I twigged. They were talking about my sunflowers!
