It's not about not dwelling, Peter. I think... When we think of them and want their company, they're with us. It's hard being sad, and it's hard to want something you can't have, I understand it very well. I just think it's important. It's because they're important to you that you feel this way, so it means something. Dwell as much as you'd like.

(it's 200-year-old wisdom, even if it comes from a teenage boy.)

Besides, you have a chance, still. We don't know what this place wants from us, maybe you'll see them again.
