　　It was a terribly rainy wet winter day. While I was walking from the library, a man was walking towards me with two huge boxes of brochures (小册子)．

　　I thought，"What on earth is that man trying to do? Carry all those things?" Then all of a sudden he dropped them all. It was a terrible mess with hundreds of brochures all over the path in front of me! "Oh, no,"I thought. The man sat down and started trying to pick all of the brochures up. I was surprised how many people passed by without even caring at all.

　　I thought，"I'm not going to be one of those people who don't care about this man. I'm going to help him." So，even though it was the end of my lunch break from work and I would be late if I stopped to help him, I didn't mind. If I explained what happened, I was sure my boss wouldn't mind too much. So, I helped him pick them all up. Then I asked if he would like a hand in carrying a box to where he went. He said yes gratefully.

　　I carried one of the heavy boxes. The box I had to carry was very heavy-as I'm quite a petite (娇小的)girl but I didn't complain. I just helped him with a big smile across my face. We got there and he thanked me very much for helping him out. He also gave me one of these lovely brochures.

　　What is a better way to spend my lunchtime than helping someone？Luckily, I wasn't even that late back to work, so nobody minded at all.
