根据短文内容，回答下列问题。

    Maria is a beautiful young girl. She has long blonde hair and blue eyes. But she is still very insecure(缺乏信心的). She often thinks most of her friends are more beautiful than her. One day a new girl joined her class. Her name is Sarah. She has dark brown hair and green eyes. Maria thought the new girl was beautiful and wished she looked like her. One day she decided to take action.

    She went out and bought some hair dye（染发）. When she returned home, she told her mother what she planned to do.

    "It's your decision," said her mother sadly. "But I think you look beautiful as you are."

    Maria didn't hear what her mother said. She spent a few hours dyeing her hair dark brown. She felt much better and went to school happily the next day. As she reached her class she saw a new blonde girl sitting near the front. Later she knew it was Sarah. Sarah dyed her hair blonde. It was almost the same color as Maria's was before. Sarah turned around and Maria spoke to her.

    "Why do you dye your hair?" asked Maria.

    "Well, I always love your hair' said Sarah.

    Maria sat down and sighed(叹气).
