After she handed in her test paper, she was certain that the test had not gone well. With a heavy heart, she left the classroom.
That afternoon, Daisy left school to work part-time at Beckman's. After she finished her work, Mrs. Beckman called her into the office. "Daisy," she said, "you have been a great worker. But business has been slow; we have to let you go."
Feeling down, Daisy left the office. As she walked slowly towards her aunt's house, she tried to think about the new hairstyle her aunt had promised her. When she arrived, Daisy showed her aunt a picture of the style she wanted.
"Well, you're done. What do you think?" Her aunt asked about an hour later.
What Daisy saw in the mirror left her speechless. It was nothing like the picture! How could she possibly go to school again?
The next morning, putting her things in her locker, she ran into Ms. Wilson, her science teacher.
"I know, Ms. Wilson, I did very poorly on the test. It's just that I forgot…"
"What are you talking about? Daisy, you did a great job!" Ms. Wilson said. "What I wanted to ask you is if you would be interested in working a few days a week after school as a lab assistant (助手). I need some help organizing all the materials." Daisy happily accepted.
"Daisy!" she heard as the rest of the students began to enter the building. "Where did you get your hair done?" She was so excited about her test and new job that she had completely forgotten about her hair.
"Wow! That is so cool!" she was told. She couldn't believe her ears. Everyone loved her hair.
What a couple of days it had been! Walking home, she smiled as the radio of a passing car played the song "What a Difference a Day Makes".
