I took a composition class with 300 words.

When I was five years old, a shocking thing happened, which was a painful lesson. I just understand, and I don't understand those abstruse concepts at all. I only know how to play, 24 hours a day. Sleep after eating and play after sleeping, just like a lazy pig lying in a pigsty, which consumes precious time unnecessarily. For me at the age of five, life is like a dream, but this is a dream.

I was very busy at home that day, and no one played with me. When I saw the bike, I was curious and couldn't help climbing up to play. So I climbed up quietly while my family was not looking. Because I don't know where the "squeak" sound came from, I was scared to sneak around, accidentally stepped on it, rolled and crawled, and my bike fell to the sky. Then, I felt that I was seeing stars and passed out.

When I woke up, anxious faces around me stared at me. I'm already in the hospital. Tears welled up from my eyes, and I only felt severe pain all over. My leg is swollen, my forehead is bleeding, and I am a little dizzy. I blame myself for being playful. If I had just sat there, such a painful tragedy would not have happened. I didn't want to endure the pain of injection, tried the bitter taste of medicine and lay down again. Is this a lesson?

I learned my lesson. It turned out to be so terrible. I know better that I should consider the consequences before acting. I don't want to make the same mistake again. I will always remember this lesson.
