[Swearing in the same sentence as mentioning Santa, in this little festive area...? It turns a few heads in disapproval, but before anyone can scold, Papyrus is close enough to chime in.]

Oh, Santa doesn't stand on ceremony! You don't have to be too adult about it... You can just send casual letters in. No itemized invoices or forms in triplicate required.

[That's meant to be reassuring, compared to how paperwork for other major officials can get to being. At least Santa offers a clear, friendly arrangement with simple terms: be good, request presents, receive presents. Something any skeleton can embrace going along with.]
