A 500-word essay about courage and courage

I was so timid when I was in the school classroom. One time the teacher wanted to ask us a very simple question, and other students raised their hands without hesitation. I knew the answer to this question, but I still didn't dare to raise my hand. Was it because I was afraid of saying something wrong? Are you afraid that your classmates will make fun of you? Are you afraid that the teacher will criticize you? But I already know the answer, is this so cowardly?

And I am so bold in life. Every day after school, I always have to cross a road, and my courage when crossing the road is so great. No matter if there are many cars or few cars, I will not do it. Hesitantly walked across the zebra crossing. One time, my brother and I were playing badminton. By accident, my brother hit the ball into the yard of a very fierce uncle's house. The uncle did not allow anyone to enter his house except his relatives and friends. My brother and I discussed it and decided to walk into their house to pick it up. Fortunately, my uncle didn't see it, so I picked it up secretly. Is this how brave it is?

I think it would be nice to be as bold as this in my studies in the future. But to be bold, you also have to be careful!
