Private letters are those letters written to our mother, father, brother, sister, uncle, aunt, friend and other relatives. These letters are written to strengthen the bond between those people. Such letters bring the hearts together. But sometimes, they weaken the hearts. Anyway, we are in a world where are civilised to write letters. The E-mails might take the place of letters. Since e-mails reach the receiver very quickly, we prefer e-mails to letters. In spite of the advantages that e-mails have, letters stand the time and become part and parcel of our lives. Here is a very good collection of letters which are usually written by us in our lives. You can improvise these letters so suit your needs and demands.
