My Visit to Sylhet

By
 Sylhet is one of the most beautiful places in Bangladesh. It's a place of natural beauty. Sylhet is widely known for having tea gardens and hills. It is also a holy place as it is known as the place of 360 awlias(saints). Last year I got the opportunity to go to Sylhet. I visited Sylhet with my family. We went there by train. I sat beside the window and enjoy the scenes through the window. I was overwhelmed by the natural scenes. After seven hours long journey, we reached Sylhet. We visited all the places of tourist attractions like- Jaflong which is near the Indian border, Ratargul swamp forest, Lauachara forest, and Tangua Haor. We spent five days in Sylhet. I enjoyed each and every moments of my Sylhet tour.

My Pet (Bird)

By
Birds are the beautiful creature of almighty. I love birds. That's why on my last birthday my brother presented me a parrot. I call it Mithu. It is very beautiful. It has a red beak, long tail, and green feather. I give it foods and water. It loves to eat seeds, rice, chilies, and fruits like mango, guava. Mithu is very intelligent. She can imitate people's voice. She says almost anything that we talk. When I go to school, I put her on a cage. When I come back from school, she becomes very happy and starts shouting. She always prefers to be among us and get pampered by us.  Mithu is not only a bird but also a very good friend of mine. I love her company more than anything else. She is loved by all of my family members. We are really grateful to have her in our life.
