Andrew lived like a prince. He slept in his bed;he had milk and chocolate for every meal. Andrew could do what he wanted. His days looked like our brithday. And when Andrew had his birthday, he hat two candles on his cake for every year, not one.

But Andrew wasn't happy. People laughed when they saw Andrew in his best coat or nice boots.
