composition

You were hiking with your friends near a lake when you saw a chest floating on it.

- What did you do?
- What did you find inside the chest?
- What happened next?
- What happened in the end?

My composition:

''Oh!I am so tired!''I exclaimed.
''You are not the only one who is tired.''Christine gasped.
''Can we rest for a while?''Mike asked with exhaustion.We sat on a big rock that was near a lake. We took out our water and food and consumed it.I was eating my sandwich when I saw a chest floating on the lake.
''There is a chest floating on the lake!''I exclaimed with my mouth full.Christine and Mike looked at the lake and spotted it out.Mike jumped into the lake and took the chest.Lucky for him, the lake was not that deep.He came back to shore and opened the chest.There are a lot of variety of diamonds!
''We are rich!We are rich!''Mike shouted like he was crazy.We jumped up and down, feeling very happy.
''Each one of us will get one third of the diamonds.''Christine said.
''But,I was the one who discover this chest.''I complained as I was greedy.
''I was the one who get the chest.''Mike said, feeling unhappy.
I pulled the left side of the chest,Mike pulled the right side of the chest.Christine tried to persuade us to stop but we turned a deaf ear.In the end,the chest flew off into the lake.
''It's all your fault!''I blamed Mike.Mike replied the same words.We went to the lake and realized that the diamonds are only stones with glitter.We were very disappointed.
''I sorry that I shouted at you all because of my greediness.''I apologized to Mike.
''I was in the wrong too.''Mike replied.
''So,are we still friends?''I asked.
''Definitely!''Mike replied with happiness.We hugged each other,Christine smiled.After that,we went home in our separate ways.
This is the most unforgettable experience to I had.
