Ben is now fifteen years old. He is interested in collecting coins. He has been collecting them for three years. He can still remember how he started to collect them.
Two years ago, on a Saturday morning, Ben was bored.  He didn’t have anything to do. He wasn’t interested in doing anything. He didn’t want to watch TV or listen to the radio. He didn’t want to play sports or read books. “I’m bored,” Ben said. “What can I do? I want to do something interesting.” Ben’s father had an idea. “I have an idea,” his father said. “Why don’t you collect coins? Coins are fun to collect. And coins are everywhere. You see coins every day. Some coins are valuable. They will make you rich.” Since then, he has been collecting them from his parents.
Now Ben has a big piggy bank (存钱罐) which is filled with coins. Sometimes he can take some of them to buy some snacks with his parents’ permission. In March, 2012, there was an earthquake in Yunnan, and Ben donated many of his coins to help the homeless children in Yunnan. He said he was happy to help others who are in trouble.
