| "I was in Bogota and waiting for a lady |
| friend. I was in love, a long time ago. |
| I waited three days. I was hungry but   |
| could not go out for food, lest she     |
| come and I not be there to greet her.   |
| Then, on the third day, I heard a       |
| knock."                                 |

| "I hurried along the old passage and    |
| there, in the sunlight, there was       |
| nothing."                               |

| "Just," Vance Joy said, "a butterfly,   |
| flying away."                           |
