Tom walked into a shop.It had a sign outside,"Second hand clothes bought and sold."He was carrying an old pair of trousers and asked the owner of the shop,"How much will you give me for these?"The man looked at them and said,"Two dollars."
"What?"said Tom ."I had guessed they were worth at least five."
"No,"said the man,"they aren't worth a cent more than two dollars."
"Well,"said Tom,taking two dollers out of his pocket,"Here's your money,these trousers were hanging outside your shop.The list price of them was six dollars and half.But I thought that was too much money,so I wanted to find out how much they were really worth."
Then he walked out of the shop with the pair of trousers and disappeared before the shop woner could think of anything to say.
