Dear Sam
How are you my dear friend? I am fine here and hope the same for you. My summer vacations has just finished and I want to tell you how I enjoyed with my family in the hill station of Shimla. The weather was very pleasant there. We had to wear woolen clothes in the morning and evening. We went to the local bazar there and bought some wooden clothes. We went to the famous Mall Road.....I did a lot of shopping there and bought a lot of things...We had great fun there.
(You can add 2 more paras on more info about what u did in the trip and what you saw there etc...I could only think of these many details....Pls add more as per convenience)
Give my regards to your parents. Hoping to meet you next month.
Yours Lovingly,
Aditya
