Tear Jerker / The Little Prince

• The exchange between the narrator and the Prince in chapter 6.
  "One day," you said to me, "I saw the sunset forty-four times!" And a little later you added: "You know — one loves the sunset, when one is so sad..."
  "Were you so sad, then?" I asked, "on the day of the forty-four sunsets?" But the little prince made no reply.
• In chapter 7, the aviator accidentally dismisses the prince's fear of losing his rose, and desperately tries to comfort him when he cries, but doesn't know how.
  I did not know what to say to him. I felt awkward and blundering. I did not know how I could reach him, where I could overtake him and go on hand in hand with him once more.
  
  It is such a secret place, the land of tears.
• When the prince finally realizes that he must return to his rose, and consequently must abandon his now-tame Fox. It's worse if you've seen the 1974 movie, where the Fox is played by the gentle Gene Wilder.
  "Ah," said the Fox, "I shall cry."
• The Fox's last lesson for the prince, especially if you think of its importance near the end of the book... say with the laughing stars:
  And now here is my secret, a very simple secret: It is only with the heart that one can see rightly; what is essential is invisible to the eye.
• "I stopped in my tracks, my heart torn asunder; but still I did not understand."
• The prince revealing he is leaving, and the aviator's response:
  "I shall not leave you."
• The end when the little prince returns to his asteroid. Or, if you interpret it differently, the prince returns post-mortem.
