Dearest Urvi,

I was so glad to hear from my mother that you are back home after such a long trip. Hope you had a safe and enjoyable trip. I have been waiting to hear all about the trip from you.

Since this was the first time you have been to a foreign land, I guess every little bit of the trip was as exciting as you expected it to be. I have heard from my friends residing there that the place is extremely beautiful and that the people there are very endearing. However, I was worried when I knew that there were a few bomb blasts during your stay there. Hope all of you there were safe. I hope everything else was fine except for this.

I had spoken to your mother earlier, and she told me that you would be coming home after two weeks. I saw your pictures on Instagram as well. I can’t wait to meet you and hear all your stories. Waiting eagerly for your reply.

Your loving cousin,

27th November 2022,

Dear Richa,

I hope you are doing well and enjoying your summer vacation. It is a well-deserved break for you after all the hard work you did in your class 12 Board Exam. It must feel good to just relax at home and play cricket with your friends. I really enjoyed visiting your place last week. Your mother is a wonderful cook and I keep raving about her cooking to my family all the time.

When I visited you, there were a few discussions about what vocation you would like to choose since the board exams are over. Yesterday, I came across an interesting article in a newspaper which can help you make up your mind. The article was about tourism. I know, you have a passion for traveling, meeting new people, and discovering new places. So, thought that a career in tourism would be perfect for you.

You should also do a certificate course with a travel agency. After completing any of these courses you could work for the government or any private firm or you could even start yours. 

Your loving,

Dear father,

I received such a nice gift from you on my birthday. My joy knew no bounds. This book gives me a lot of knowledge and vocabulary. Although a good number of my friends and relatives attended the birthday party. Yet I missed you all the time. My friends and relatives gifted me many things but your gift of a dictionary are unique in many aspects. This gift is a great source of joy for me. It will help me to cultivate the habit of reading good books. I shall preserve and treasure it throughout my life. 

Yours Lovingly,

Pragya Pandey
