An old birthday celebration... Well, I would hate to hurt anyone's feelings. Not on their birthday.

[The used to time she means must have been a long time ago indeed, to look at the differences between the festivities around them and any birthday celebration he's been to. Sure, there's colorful decorations, and presents, and costumes - even some fire. But all the emphasis is on giving and getting presents, instead of... whoever's birthday it is. He doesn't even know who - which god, and which son? He's pretty sure Santa doesn't have a kid, right?]

I'll pick one... or maybe two, to pick between.

[If he includes a note to only give one, that's practically not greedy at all.]
