How to say goodbye?(口白)

Hey Siri. How do you say goodbye to someone you can’t imagine living without? The question is too difficult to answer. What would you say? I didn’t say goodbye. I didn’t say anything. I just walked away. Are u still feeling sad? Of course, but u know——not every encounter has an end, but each meeting carries some meanings. Yes, some people are there to help u grow. I wish them happiness.
