这种留言条在日常生活比较常见，与其他类型的便条并无本质上的差别。一方面作者说明，他已经按朋友的要求来车站接人了，但由于双方面的原因，不得不离开。先说明离开的原因，然后交待清楚取得联系的方法。因为二者是朋友关系，语言并不要求特别正式。

　　你到火车站去见你的一个朋友，火车还没到，所以你必须在剪贴板上给他留一张便条，他从中学会如何找到你。
　　You go to the railway station to meet one of your friends,and the train has not arrived yet,so you have to leave him a note on the clipboard,from which he will learn how to find you.
