Grandparents refer to the parents of a person's parent, or the mother and father of one's mother or father. In other words, they are the biological parents of an individual's own parents. Grandparents often play an important role in their grandchildren's lives by providing love, support, guidance, and wisdom. They can be a valuable source of family history and traditions, and can offer a unique perspective on life experiences that may benefit their grandchildren as they grow up.
