Old man Juan Carlos was in the operation room, waiting for his son, a noted cardiologist, to perform a surgery on him.
Before the assistant doctor could administer anesthesia, Juan Carlos requested that he be allowed to speak to his doctor son in private. When they were alone, Juan Carlos said, "I love you, my son. Do not be nervous. You have many years of experience behind you so give it your best shot. If something goes wrong, just remember that your mom is gonna move to your place permanently to spend the rest of her life with you and your wife."
