    While waiting for my daughter I treated myself with a coffee which I used to be so dependent on that when I stopped it I had headache for days. So while I was enjoying my rate moment, I was attracted by an old men who seemed not well

    I could not see his face to be sure, as it was laid between his folded arms on the table. He had a long warm coat, and a big backpack which made me think he could be a homeless. I quit wondering, went to his table, patted him on the arm and asked him, “Are you OK?” He raised his head and said something in a whisper, nodding yes. I realized by the strong smell that he was indeed a homeless man.

    I asked him if he was hungry. He responded but I could not understand his answer. However, I didn't give up and asked him if he would like some rice balls at which he raised his head saying clearly this time that he would be thankful for a rice bait Immediately I went to the nearest shop and bought a drink and a warm lunch box, and brought them to him. He said “thank you” but didn't eat right away and made no move, maybe because he was a little shy in the presence of a lady.

    So I left them on his table and changed my waiting place. When I passed again nearby, he was eating. You should have sensed my great pleasure. I was so grateful that I had the ways to help an old man even if only for a moment of his life.

    咯吱，咯吱，主人的两腮满是白花花的肥皂沫，他正对着镜子，聚精会神地刮胡子。

    小花猫在一旁仰着脑袋，碧绿碧绿碧绿的大眼睛，一眨不眨地看着主人刮胡子。

    主人刮完胡子，走了。

    小花猫觉得自己的胡子老长老长的，太难看，就学着主人的样子，也把胡子刮得干干净净的。

    晚上，小花猫追捕老鼠。老鼠很狡猾，从墙上一个小洞里钻了过去。

    小花猫追了过去，却一头撞在墙上，撞得鼻青脸肿。

    猫妈妈看见了，耐心地对小花猫说：“你的胡子好比一把尺子。你能不能从洞里钻过去，先要用尺子量一量。你把尺子刮掉了，当然会碰得头破血流！”

    从那以后，小花猫再也不刮胡子了。
