      The phone rang loudly next to her ear as she sat at the computer. Sarah picked it up; hoping

it wasn't for her, because she really didn't feel like talking to anyone. She uttered a  monotonous

(沉闷的 ) , " Hello?" " Hi  Sarah! !This is Mindy! What's up?? Umm, the reason that called was

that I need help with the English assignment. I've been having trouble coming up with a topic. "

      Sarah's shoulders silently drooped as she realized that she had completely forgotten about the

homework to witness or be a part of a situation and write it in down in great detail. She let out a sigh.

       As her best friend continued to talk about her topic ideas, Sarah's mind drifted. She thought

about how Mindy was moving 500 miles away in less than a month. She thought about how much

she'd miss her friend and how it wouldn't be the same without her.

         "So, do you have any idea what I should do about this assignment? "Mindy asked, bringing

Sarah out of her fog. She answered her own question, suddenly exclaiming, "I know! !  I'll describe

what happened today in the lunch line! I just wanted to ring that Jennifer girl's neck! !  SHE WAS

SO RUDE! "'

         Sarah thought back to earlier in the day when they had been in the lunch line, waiting patiently

and a snotty(自大的)girl pushed her way up in front of them, causing Mindy and Sarah to lose their

place in line.

          "That sounds like a good idea. I wish I'd thought of that, "Sarah says softly. The conversation

ended quickly after that and Sarah was feeling better. She was still sad that her best friend was moving,

but she knew that they would keep in touch and always be close. At just that moment, Sarah was glad

that Mindy called. She now had the perfect topic for her English assignment.
