Max is asked to mail a letter for his mother. As he walks through his neighborhood in search of a mailbox, he encounters all sorts of interesting things like falling leaves dancing in the wind, skyscrapers towering in the distance, and junk being piled into a garbage truck. All around him adults hurry on their various errands, too busy to appreciate these wondrous details. His walk through the city leads Max to discover that the mailbox is actually right next door to his own house. Children will enjoy following Max on his adventure and seeing things from his perspective as they explore Joanne Liu's colorful celebration of everyday life in a busy city.

妈妈叫Max给她寄一封信。穿过住宅区寻找邮箱的过程中，他遇到了各种有趣的东西，比如在风中飘舞的落叶，远处耸立的摩天大楼，正在被堆入垃圾车的垃圾。他的周围，大人们匆匆忙着各种各样的事情，他们太忙了，以至于没时间欣赏这些奇妙的细节。走完这座城市Max才发现，邮箱就在他家隔壁。孩子们将喜欢一边探索Joanne Liu对忙碌城市日常生活的丰富多彩的描绘，一边跟着Max冒险和见识各种事物。
