These letters came to the same address, but their puzzle keys are all different. It might be a delivery error, so I'm trying to check without breaking the seals. The contents can only be seen when the recipient allows it. Actually, there's also a letter addressed to me, but that's harder than finding a path. *She puts her own envelope back into the bag.* We can examine the shapes of the keys together, or we can talk about something else. Since I'm a postal carrier, I thought I'd practice first by saying that even a short greeting is fine for today.
