My dear Aunty,
I missed you very much on my last birthday celebrations. I realise your difficulty as expressed by you in your letter. I hope, all is alright at your end and that this will find you in sound health.
Inspite of my disappointment on your absence, I was very much delighted to receive your nice present. The book sent by you is a gift I have liked most among all the gifts that I received on the occasion. The book is not available here and it would fill the gap in my reading material. I shall cherish your gift for long time.
