Personal letters are written communications between individuals, often sharing thoughts, feelings, or updates about life. They can be addressed to friends, family, or acquaintances and typically reflect the writer's personality and emotions. Personal letters can be handwritten or typed and may vary in tone from casual to formal, depending on the relationship between the sender and recipient. These letters often serve to strengthen relationships, convey important news, or express gratitude. Unlike formal letters, personal letters allow for more creativity and intimacy, making them a cherished form of communication. Examples include birthday wishes, thank-you notes, or letters of encouragement.
