A MELTING STORY
One winter evening a country shopkeeper was going to close his shop for the night.
He went out to shut the windows from outside and through the glass he noticed that a man in the shop quickly took a pound of fresh butter from a shelf and hid it in his hat. "What fun I'll have," the shopkeeper said to himself as he thought of a way to punish the man for stealing.
"I say, Seth," said the shopkeeper, as he came in and closed the door after him.
Seth already had his hand on the door, ready to leave the shop as quickly as possible.
"I say, Seth, sit down. On such a cold night as this, it is very pleasant to sit in a warm room."
Seth did not know what to do. He had the butter in the hat and wanted to get out of the shop.
But the shopkeeper took Seth by the shoulder and made him sit close to the stove.
"We'll make it a little warmer, Seth," he said and put some sticks inside the stove. "If you are not warm enough you'll freeze when you go out on a night like this."
Seth already felt the butter melting, and he jumped up and said he must go.
"Not till I'll tell you a story," said the shopkeeper and he made Seth sit down again.
"Oh, it's so hot here," said Seth.
"Sit down, don't be in such a hurry."
"But I must go. My cows... they're hungry... I must go and feed them."
Poor Seth! He didn't know what to do. The butter began to melt and came from under his hat down into his eyes and mouth.
The shopkeeper was talking and continued to put sticks into the stove.
"Fine night this," he said. "Seth, why don't you take your hat off? You seem to be warm."
"No!" cried poor Seth at last. "I must go! Let me go out. I'm not well. Let me go!"
The butter was now coming down the poor man's face and neck and even down his body into his boots, so that he was in a bath of oil.
"Well, good night, Seth," said the shopkeeper smiling, "if you really want to go."
Then he added, as Seth made his way to the door, "I think the fun I have had out of you is worth ninepence so I won't charge you for that pound of butter in your hat."
