阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。One day my grandfather gave me a gift ——a piggy bank. It had an opening through which one could put money in, but the opening was not big enough to reach in and get the money out. The only way to get at the money was to break the piggy bank open. My grandfather explained that was the whole idea:the piggy bank would help save my money so that, at the end of the year, I might have enough for that bike I dreamt about. He asked if I would put some of the money he gave me into the piggy bank. I agreed immediately and promised that I wouldn't break it open until I could afford my dream bike.
Whenever he gave me a little bit of money, he would say, "This is for spending. But you can save some and put it in the piggy bank if you want to save it up. "When he gave me larger amounts, it was clearly for saving in the piggy bank. For some time, this worked fine. I loved shaking the piggy bank and hearing the sound of the coins. As it became heavier, I grew more excited, dreaming about buying my new bike, and all the adventures I could have on it.
Whenever I wanted to take some money from the piggy bank to buy deli-cious ice-creams or beautiful pens, I would imagine riding my bike on the street, and thinking of that, my thoughts about ice-creams or pens went away. So for almost six months, I only put money into the piggy bank without tak-ing any out. I thought I wouldn't break my piggy bank for anything. But one day something unexpected happened. I saw a piece of news on the television that a serious earthquake had happened in a nearby province. As many houses were destroyed, a lot of children became homeless. Seeing their shabby clothes and crying faces, I was sleepless that night.
