In life, you are only irreplaceable to your parents, siblings, and children. Every other person can replace you. Your wife can remarry. Your girlfriend will befriend another boy. Your boss will replace you. And your friends will find other friends. But your parents cannot have another you. Neither can your siblings. And even if your wife remarries, her new husband will be a stepfather, not a father to your children. This is why doctors will ask you to bring your blood relatives if you need a compatible organ donor. Therefore, absorb this wisdom while you are still alive and step up to do something substantial and permanent for those in your life to whom you are irreplaceable. #RenosNuggets
