“Life: I'll never understand it.”

“The world's full of groundless ill will. I'll never understand it, you'll never understand it, but it exists all the same.”

“I'll never understand how a man can live his life With his finger on the self-destruct button, Holding it there day after day, Blinded by an obsession to press it But lacking the conviction to do even that.”

“I understand that you're a big fish in a small pond, but I'll explain that if you want to swim in the ocean, you must understand that the ocean is populated by sharks, and sharks never sleep.”

“It will hurt. Because deep down, I'll know there was someone.. someone I was supposed to have met. Only I'll never meet him. I'll go through my whole life waiting for him to come along, only he never will. What kind of life is that?”

“You're a medicine cat. I understand what that means now. StarClan go with you, Leafpool. I'll never forget you.”
