It was September 27th. It was George's birthday. He saw a card on the table when he came back home. It said, "There's a present for you, George. Look for it in your room" George ran into his room. His parents were looking at him and smiling. On his bed,he saw a new red box. There was a card in the box. He took it out and read, "Dear George,I'm your present. My letter is in the word 'pear', but not in 'bear'. My second letter is in 'tell', but not in 'tall', and you can find my last letter in both 'orange' and 'ink' , what am I?" George thought for a while. And soon smiled," Aha, I know. But where is it?" His mother told him it was in his schoolbag and he found his present in it. What is it? Do you know?
