Dear Nam,

I hope this letter finds you well! I wanted to share an incredible experience I recently had that I believe made a positive impact in our community.

Last weekend, I participated in a community clean-up event organized by our local environmental group. It was such a rewarding experience! Early Saturday morning, a group of volunteers gathered at the park near my house. We were divided into teams, and our task was to pick up litter and debris around the park and along the nearby riverbank.

At first, I thought it would be a simple chore, but as we began working, I realized just how much trash had accumulated. We found everything from plastic bottles and wrappers to old tires! It was eye-opening to see how much waste was affecting the beauty of our surroundings.

Throughout the day, we not only cleaned up but also learned about the importance of keeping our environment clean and how litter affects wildlife. We even had a chance to plant some trees, which I felt was a meaningful addition to our efforts. It brought us all together, and we had a lot of fun while making a difference.

I met some wonderful people during the event, and we shared stories and laughter while working hard. It reminded me of how much we can accomplish as a community when we come together for a common cause.

I think you would have enjoyed it too! I know you care a lot about our environment and community. Maybe we can organize something similar next time and invite more friends to join us.

I hope to hear from you soon, and let me know what you think about my experience!

Take care,
Minh
