It was a clear, bright morning and An An, the Ocean Park panda, decided to leave home for the day and go shopping in Causeway Bay.
At lunchtime, he felt hungry, so he went into a coffee shop and bought a sandwich. It was delicious. When he'd finished, he reached into his bag, pulled out a gun and shot it into the air. There were no bullets in the gun, but it still made a terrific bang. Everyone in the shop jumped with surprise.
An An left the coffee shop, politely saying goodbye to everyone. A man ran after him, shouting, 'What did you do that for?'
An An looked surprised. 'I'm a panda,' he replied. 'I have a book about animals in my bag and it says that's what pandas do. Would you like to have a look?'
An An handed the man the book. Sure enough, on page twenty-three, it said, 'Panda: black and white bear-like animal, native to China. Eats, shoots and leaves.'
Commas are small and are very easy to ignore. But a misplaced comma in a sentence can do a lot of damage. A comma in the wrong place can turn a sentence into nonsense or make it say something you don't want it to say.
