Letters have always been a way of communication. They have been used in many ways that are beneficial to us. When we were younger, we were taught to write letters such as friendly letters, birthday invitation letters and of course love letters. Such letters are used primarily to express feelings, emotions and thoughts. These kinds of letters are usually addressed to our families, relatives, friends and special someone. We call these letters as informal letters.
