Hand the reins over
Cornelius said, "Think about it, you nearly died because of your position."
Rufus stated, "That's true, but I was saved by you."
Cornelius sighed. "I just think that it's time for you to hand the reins over to a more appropriate candidate."
Rufus frowned. "You may be right there, but now isn't the time to just leave."
Cornelius replied, "Now's the perfect time. The Second Wizarding War is over and we won. Ruf, this is the exact right time for you to resign. There are plenty of bright young witches and wizards willing to take up the reins."
Rufus smiled ever so slightly. "I suppose that you're right, Corny. I have had my fair fill of disasters as Minister, it's time for someone else to deal with all of this nonsense."
Cornelius grinned. "That's what I like to hear!"
