Dear Kankan,
I hope everything is well with you. I am also fine by the grace of God. Recently, along with my parents, I went to Kolkata. We reached there by train. There we visit the very famous Victoria Memorial. It is one of the city’s oldest structures, but it still shines; it was built by the British. We also visited the Jumma Mosque, which is the most famous mosque in India. The next day, we went to the metro station, and it was my first time riding on a metro train, which was an incredible experience. We stayed in a hostel. Our journey was four days and three nights. Finally, we arrived safely home.
Your loving friend
