Answer:
56, Orchid Lane, Lucknow
14th October 2025
Dear Aarav,
You won’t believe what happened last Sunday we had no electricity for the entire day! At first, I thought it would be boring, but it turned out to be quite an adventure.
Without fans or lights, we sat together as a family and talked for hours. I even helped my mother cook using a candlelight. At night, we went up to the terrace and watched the stars — something I hadn’t done in years.
That day made me realize how dependent we are on power. It was a small reminder to live simply and enjoy nature more often.
Write back soon have you ever had such a power-free day?
Yours lovingly,
Riya

I’m so excited to tell you about our school’s “No-Plastic Day” last Friday. Everyone brought steel bottles and paper bags instead of plastic ones. Even our canteen used eco-friendly plates!
Our class made posters about ocean pollution, and I gave a short speech on saving marine life. It felt amazing to do something meaningful for the planet.
After that day, I promised myself to avoid single-use plastic completely. I even taught my younger brother how to make bags out of old newspapers. Small steps really can bring big change!
Write soon I’d love to know if your school does such campaigns too.
Yours lovingly,
Kavya

Dear Arjun,
Yesterday started as an ordinary day, but it turned into a movie scene! While coming back from tuition, the sky suddenly turned dark, and it began pouring heavily. I had no umbrella, so I ran to a nearby tea stall for shelter.
Strangers around me were laughing, sharing snacks, and watching the rain together. I even helped an old man carry his bags through the water. By the time I reached home, I was drenched but oddly happy.
It was a beautiful reminder that even a storm can bring people closer. Next time it rains, I might just let it soak me again!
Yours lovingly,
Maya
