阅读理解。

     I live in a very over populated beach area in the Los Angeles, and I love the beautiful scenery!

But because of many people, lots of things are easy to be out of order, and sometimes it’s also

easy to lose your cool. Today was a day I wish I did not get out of bed. I mean that if I did not

have to wake up and deal with all the things that I deal with on a daily basis, it would have been

wonderful.

     I had a cup of coffee this morning and that was my meal for breakfast, not healthy I know.

Anyway, my stomach was sounding like a truck. So, I jumped in my car and decided to buy

some food.

     I was in line at Taco Bell (一家墨西哥速食店) and the line was like a long snake! Finally I

got to place my order, but a young girl in nice clothes pulled in and was stuck in such a way that

unless I moved for her, she wouldn’t be able to get out. So I backed up and waved her into my

place in the front of the line.

     To my surprise, this young girl did not say thanks. I was cool with it because I thought that I

had done something nice for a change. After the girl received her food and pulled away, I pulled

into the ordering spot, not mad, but hungry, and the employee said, “Hi, that girl just paid for your

food.”

     That food was the most satisfying nourishment (营养品) my body had ever taken! If just by

chance you are that person who bought my food, I should say “Thank you!”
