A beautiful story

There is a little boy with a flat nose. Because I got encephalitis at the age of two, I was mentally impaired and had difficulty in learning. For example, if someone can write two or three hundred words in a composition, he can only write three or five lines. But even such a composition can be written beautifully.

It was a composition class, and the topic was "Wish". He thought about it for a long time, and then he wrote it seriously. The composition is short, with only three sentences: I have two wishes. The first one is that my mother looks at me with a smile every day and says, "You are so smart." The second is that the teacher smiles at me every day and says, "You are not stupid at all."

Therefore, it is this composition that deeply touched his teacher. The mother-like teacher not only gave him the highest score, but also recited the composition emotionally in class, and criticized one by one: you are smart and your composition is very touching. Please rest assured that your mother will like you and your teacher will like you. People are sure to like you very much.

He took the composition book and skipped home like a magpie with a smile. But he didn't show his mother the composition book. He is waiting for a wonderful moment.

That moment finally arrived. It was my mother's birthday-a sunny Sunday. That day, he got up early and put his composition book in a beautiful big envelope made by himself. On the envelope, a boy grinned sweetly. He looked at his mother quietly, waiting for her to wake up. As soon as his mother woke up, he called out "Mom" sweetly, and then walked up to her with a smile and said, "Mom, today is your birthday, and I want to give you a gift."

Mom smiled: "What?"

He smiled: "My composition." He handed me the big envelope with both hands. After receiving the envelope, my mother's heart was pounding!

Sure enough, looking at this composition, my mother shed two lines of tears sweetly, and then hugged the little boy tightly, as if he would suddenly fly.

Yes, intelligence will be impaired, but love will never. It is full of vitality, always hanging in the shade, with bright flowers and fragrant fruits.

Mother's pure water

A bottle of ordinary pure water, two dollars; A bottle of famous brand pure water, three yuan. It's really not expensive. When I was in physical education class, many students brought pure water to prevent me from quenching my thirst after strenuous exercise.

So is she. Her pure water belongs to Robust. On the green trademark, the handsome Dawn is dressed in white with a clear and shy smile. Every Tuesday and Friday at noon, after lunch, my mother took out pure water and handed it to her. She always feels a little uneasy when she holds this bottle of water. The economic situation at home is not very good. My mother has been laid off for a long time, and my father's salary is not high, but she feels happier and more satisfied, because my mother has given herself face in this matter after all, which is probably the only thing that keeps up with the fashion in her work and keeps up with those fashionable classmates.

I went to physical education class, but my deskmate didn't bring pure water. Naturally, she handed her water.

"Hey, your water doesn't look like pure water." The deskmate took a sip and said.

"How?" Her heart was pounding. "My mother just bought it today."

Several students gathered around: "It can't be fake, can it? Fake is cheap. "

"You see, the date of production can't be seen."

"The color is also a bit awkward."

A classmate picked it up and tasted it: "Hey, it seems cold and white!" " "

There was a silence and everyone laughed. Yes, like cold water. In an instant, she suddenly realized soberly that the pure water she had drunk for so long might really be cold and white. Otherwise, how can a thrifty mother be generous in this matter alone?

She threw away the bottle of water at once.

"Is the pure water you gave me cold and white?" On entering the room, she asked her mother.

"yes." Mother said, "There is too much fake pure water outside. I am afraid that you will drink bad, so I will give you cold boiled water. " She gave her a look. "Did anyone say anything about you?"

She kept silent. Mother is so hypocritical, she thought, obviously to save money and for my own good.

"Of course, it can also save money." Mother seemed to read her mind and said, "Do you know? This family uses seven tons of water a month, which is 85 cents, almost 6 dollars. If I buy you pure water and go to physical education class twice a week, it costs six yuan, which is enough for our family's water bill for one month. In this way, you can save 100 yuan a year and buy a lot of chickens. "

Mother was right. She knows. As the only pure consumer in the family, she has no ability to earn money for her family, and always has the obligation to save money for her family-besides, drinking cold boiled water and pure water really makes no difference to her body, but she still feels aggrieved and bitter.

"Classmate, is anyone laughing at you?" Mom asked again.

She nodded.

"Then listen to my thoughts." Mother said, "It is true that we are poor. However, you have to understand these truths: First, there is nothing wrong with being poor, and there is nothing wrong with being rich. Poverty and wealth are a way of life. Second, the poor are not pitiful. People who laugh at the poor are poor. With how rich he is, fundamentally speaking, which family has no generations of poor people? Third, no matter how poor you are, you must respect yourself. If you look down on yourself, your heart will be very poor. Poor heart is really poor. "

She nodded. That night, she thought a lot. At dawn, she really wants to understand her mother's words: poverty is really nothing. This is not an honor, nor is it a shame; It's just a comparative state of life, a status quo that she needs to understand and change. If she regards it as an ugly dress, then it really obscures her inner light. If she regards it as a wide cloth, then she can make it into a warm new dress-even, she can make it into the kind of curtain in the hands of a magician, and use it to change a colorful future and dream.

That's it.

Later, she went to physical education class with cold boiled water poured by her mother in her hand. Some students deliberately asked her, "Is it cold and white inside?" She looked at the questioner calmly and said, "Yes."

Later, she was admitted to the university and found a good job with high salary after graduation. She can drink all kinds of expensive drinks at will, not to mention pure water. However, as long as she is at home, she still likes to drink cold water. She told me that she had never drunk pure water better than cold boiled water. (Prose Baijia No.2002 10)
