My Dear father
I received your letter yesterday. I am fine. I am glad to know that you all are safe and sound. In the letter, you have wanted to know about my hostel life. Here, I am giving you a brief description of it.
The environment of my hostel is very charming. There is an open field in front of my hostel. I and my friends play here every afternoon. My hostel life is very happy and enjoyable. I can study here attentively. All the students are very helpful and friendly. Living here, I get opportunity to follow some rules and regulations. The foods are of high quality. The canteen and dining room are also neat and clean. In a word, I feel very happy living here.
No more today. My best regard to you
Yours affectionately
