Composition: My sister.

My sister Yanyan, she is very happy all day. As the saying goes, women laugh without showing their teeth. But she didn't care, and even her front teeth were exposed when she smiled, which was not like a lady at all.

I remember once, she and I went to the bookstore to buy books. She bought a "joke" and read it as she walked home. I couldn't help laughing at the beginning. After reading a few words, I laughed. That laugh was strange. Passers-by stared at her strangely, as if to say, "Is it so funny?"

Seeing the middle, she stroked her stomach, holding a book in her hand, and said to me, "Sister, this joke is really funny …" Before she finished, she burst into laughter. That's a great smile. She sat on the ground and smiled and said, "Sister, give me a hand." I rushed up and quickly pulled her up. However, I dropped my ice cream. It landed right on my shoes.

I didn't expect her laughing nerves to attack again. She has a book in her right hand and her left hand is pointing at my shoes. She smiled and said, "Oh, my shoes are embroidered with flowers. How beautiful! Haha ..... "I was shocked and thought: It's so funny again. It's just that an ice cream fell on the shoes. Who can laugh? Is her laughing nerve this strong?

Unconsciously, we arrived at my second aunt's house. Aunt's house has guests today.

The second aunt saw that her sister was still laughing, so she opened her mouth and scolded, "You dead girl, you keep laughing all day. Have you laughed enough? "

My sister said slowly, "Aunt, you laugh too! You have too many wrinkles. Laughter makes you younger. Make sure you are ten years younger. " My second aunt laughed, followed by a room full of people laughing.

That laughter almost collapsed the roof.

"Ha ha ha ha ....." Sister burst out laughing again. ...

Why does my sister laugh so much?
