Fortune is with September in two ways. For one, Diarmuid knows deep down that everyone will eventually have to go home. They all have things to do, including himself. Because of that, even though he is sad at the idea of September going away, he doesn't start crying again. It is going to happen to them all someday--they will leave and not come back--but who knows when that will be? As he has been told by many and is trying very hard to believe, it is better to focus on the time they have than what they won't have.

And second, sadness has never stayed with Diarmuid long. It might not pass as quickly as it did before he lost that thing that was so important to him--that thing he can't remember--but it still passes quickly. Besides, his curiosity has been awakened and it is much more fun to be curious than sad.

"Yay! I got to help you! I am so happy!"

Oh, and that too. It's really hard for him to be sad when he knows he just helped someone.
