The Pot of Gold Tom Fitzpatrick was out walking one morning when he saw a very, very small man with a green jacket and a red cap sitting under a rock on the grass, fixing a shoe. Tom was very excited because he knew that the little man was a leprechaun. Leprechauns are magical people. They say that if you follow a leprechaun, you will find a pot of gold. But if you take your eyes off him for one moment, he will disappear. "Good morning," said Tom to the little man. "What are you doing?" "That's not your business," said the small man in an unfriendly way. Tom got angry and picked up the little man, saying, "Tell me now where you have put your gold, or I'll never let you go!" The little man was frightened. "All right," he said. "I apologize. I'll show you where the gold is if you let me go." And Tom agreed. So off they went. The leprechaun went in front, and Tom never took his eyes off him. They walked for a long, long way. Finally they came to a field that was full of different herbs. The leprechaun pointed to one of the largest plants and said, "See that big plant there? Dig under it and you'll find a pot full of gold." Tom knew it was true because leprechauns never lie. He couldn't wait to get his hands on the gold. But he didn't have a shovel to dig a hole. He would first have to go home and get one. So he took a red handkerchief from his pocket and tied it around the plant so that he would remember it. "Now," he said to the leprechaun. "Promise me that you will not remove this handkerchief until I come back" "I won't," said the leprechaun. "May I go now?" "All right then," said Tom. "You may go, and good luck to you!" He went back to his house to get a shovel, and then he ran back to the field as fast as he could, with his shovel on his shoulder. But as soon as Tom returned to the field, he knew that the clever leprechaun had played a trick. Every plant in the field had a red handkerchief on it, and each plant looked exactly the same! Tom dug first under one plant, and then under another, for many hours, but in the end he had to go home, dirty and empty handed. Are the sentences true or false?
