Yesterday is Mary’s birthday. After class, we walked home together. We talked for a long time and had an appointment. We would be friends forever. We all said that no matter what happens in the future, we will be friends forever. We were neighbors and we played together when we started to remember things. We often heard the adults say that many things will change as we grow up. But we believe our friendship will not change forever, so we have our deal. 
昨天是玛丽的生日。下课后，我们一起走回家。我们聊了很久，并且有了一个约定。我们永远都是朋友。我们都说，无论将来发生什么事，我们永远都会是朋友。我们是邻居，在我们开始记事时就一起玩了。大人们常说，等我们长大了很多东西都会变的。但我们相信，我们的友谊永远都不会改变，所以我们有了这个约定。
