陳豪工作的公司裏有一個公用的廚房，裏面有冰箱，咖啡壺，微波爐等供工作人員使用。還有美籍華人Mary剛走進廚房，看見陳豪有點不知所措的樣子。
(Office ambience)
M： Hey, Chen Hao, what happened?
C： Someone ate my lunch! 早上我買了一盒土豆沙拉放在冰箱裏。現在沒了！
M：Gone? Did you have your name on it?
C：Write your name on the box？是不是自己的飯還不知道呀？我要收藏
M：外面買的飯，盒子看起來都差不多不少。If you don’t have your name on it, 別人拿錯是很有可能的呀！
C：那倒是。不過，發生了今天的.事， I don’t think I’ll ever forget to put my name on my lunch。
M：不過這冰箱確實是個大問題。 Sometimes people bring their lunch, and later decide to go out to eat and forget about their food in the frig until it starts to smell。
C：是呀，有兩次我看到有東西都發黴了。I just have to throw them out. 得了，別說了，真噁心。I have to find some lunch。
M：See you later。
C：Hi, Mary, ready to go home? Can I walk with you?
M：Sure. By the way, did you find out who ate your lunch?
C：Oh, yes, I did. It was all a mistake. Brian太忙，讓William給他帶個沙拉回來放在冰箱裏。Brian 去冰箱拿沙拉的時候William還沒有回來。他以爲我的沙拉就是William替他買的，所以就吃了。
M：原來如此。 But we do need to remind people to observe simple kitchen courtesies。
C：Simple kitchen courtesies? 廚房裏還有禮貌呀？
M：當然有呀！For example, if you drink the last cup of coffee, you should fix a new pot for others。
C：我同意。有兩次，我想喝咖啡，可是到了廚房看見的是空咖啡壺。I have to make a new pot and wait for a long time to get the coffee ready。
M： Also, it’s just good manners to clean up after yourself such as wiping off the counter and throwing away the trash。
C：噢，擦桌面和扔垃圾！這我倒是沒有想到，因爲在家裏這些不是我媽，就是我姐姐做的。不過，Next time, I should pay more attention to it。
M：You also have to remember: keep the refrigerator clean -- put your name on your food and throw away any unwanted food; make a new pot of coffee when you drink the last cup. Throw away the trash, and clean the counter。
C：Thank you, Mary.
