The Parents, also known as Mom and Dad, are two unseen characters that will write letters to the player, though they cannot be written to. Mom tends to write more letters than Dad, who will only write on Father's Day.
Mom tends to write a small little story or joke about life in the character's home prior to moving into town. These tend to be words of wisdom or guidance. Sometimes these letters will have a gift attached, usually fruit.
Dad will only write on Father's Day and sends the player a red carnation.
