Philip is a school boy. On his twelfth birthday, he decided to give up eating 1.
"I don't think it's right to eat animals," he said. "They live on the Earth just like us and they are our friends." Philip's parents were not happy about that. "You are a growing boy," his mother said "You need meat. Don't you want to become healthier and 2?" His mother put some 3, rice and carrots in front of him. "I want you to eat all your food now," she said. "Don't 4 anything." Philip didn't want to make his mother sad. But he ate only the rice and the carrots without touching the beef.
"You're a silly boy!" said his father 5. "I'm getting very angry with you."
"I'm sorry, Mum and Dad," answered Philip. "I don't want you to be sad or angry. 6 I really don't want to eat any meat. "
"Then have some fish, dear," said his mother.
"Oh no, I can't!" cried Philip. "Fish are living things, too.
"Well, you can't have 7 to eat at all if you don't eat any meat or fish," said his father.
The next morning Philip got up hungry. His father walked to the 8 with him and asked to see the teacher. "Is this what you teach the students at school" he asked the teacher. "Philip 9 to eat meat at home. He doesn't listen to what I say. "
"I don't agree with Philip," replied the teacher. "But I think he is 10 to do what he thinks is right. We teach the students to do that."
