Draft a letter inviting a friend to spend summer vacation with you.
I am sure this will find all of you in the best of health as it leaves us here.
Schools are closing for summer vacation from 18th next and I suggest that you should all come down to this place and spend the vacation here. Dehradun is a very nice place and people come from far and wide to spend summer here. We have not met far quite some time and this will give us an opportunity to spend a few days together.
I shall await for your reply.

I am grateful to you for your kind invitation.
I have not seen Dehradun and it would have been really a great pleasure for me to come to that place and spend a few days together with one of my dearest friends. But, dear Swati, my respected father is suffering from typhoid for the last five weeks and it has lapsed twice. Doctor has advised proper care for him. I being the only four members at home, it is almost impossible for me to leave my father alone. Vacation is for two months and in case my father improves, I shall plan to come here for a week or so.
Rest everything is fine.
Yours as ever,
