Setting the ending to years later was a smart idea, it gave your ending such a nice atmosphere, especially with the lovely description in the beginning. The dialogue really felt like old friends talking, and the story they told to Lucy was compelling. Burning down half the park and having that lead to true love? Unexpected in a great way, and having Sarah chime in at the end brought it to a nice close. I can easily imagine them continuing past the final line, maybe reminiscing more over dinner.
