Suppose, you are Kamal/ Kulsuma and your friend Jamal/ Jasia. Now, write a letter to your friend inviting him/her to join the picnic.
I received your letter yesterday. From your letter, I have known that your Annual Examination has ended. Our Test Examination also ended. Some of my classmates have decided to go on a picnic at Rangamnti on Friday next. Our Bengali teacher Prof. Kalaln Mahmud will also accompany us. On Friday at 7 o’clock in the morning, we shall start to Ranganati from our college on a minibus. We shall take all necessary foodstuffs, utensils, and musical instruments with us.
We shall spend the whole day at the site of the picnic and enjoy ourselves freely. After sun-set, we shall come back to Chattogram by the same bus. We shall be very glad if you accompany us. I am sure, you will have a nice time with us. Do come to our college early in the morning on Friday. Please bring your camera with you.
I am quite okay. Give my regards to your parents.
With love and best wishes,
Your loving friend
