Today was the Hungry Luncheon (饥饿午餐日). Every year, at our school, there is a lunch event called the Hungry Luncheon.

If you want to join the event, you must pay two dollars at the door of the dining hall and get a letter. All the money is used for helping those poor people who don’t have enough (足够的) food to eat. My letter was “K”.

After all the students sat down, the teachers called the letters for the meals: 15% of the students got to eat a best dinner. 25% of the students got to eat an Okay meal. But 60% of the students just had a small piece of bread and a small cup of water!

The purpose (目的) of this event is to tell us about the unfairness (不公平) of the world, and that we need to start helping the poor!

I was one of the 60% of the students. I was a little hungry for the rest of the day, but I learned something from this special lesson. Now every time I eat, I think about the poor.
