Write a letter to your niece inviting her to your house.
14131, Shakti Nagar
May God bless you with happiness! I hope you are fine by the grace of the Almighty. I received umpteen letters from you. But I could not send any prompt reply to them since I was awfully busy with my work. Today finding some free time, I am writing this reply to you. You have written that since there is no high school in the village, your studies remain incomplete. You need not worry on that account. Here there is a Govt. Senior Secondary School where studies are up to the mark. Your maternal uncle is coming next Sunday to bring you here. So you should accompany him. Here we shall make all proper arrangements for your studies.
With kind regards to sister-in-law and love to children. Waiting for a reply to my letter.
