Dear Receiver: someone wants something. Whether the Bearer’s fondness for the Receiver is romantic, platonic, familial or noticeably ambiguous is irrelevant here – what marks this communication as important is the favour. It might be as simple and mundane as tracking down the Bearer’s lost cat, or as elaborate a scheme as posing as a paramour during an important social event. The task might seem odious, but it is surely somewhat uncivil to turn down a request so eloquently delivered. Furthermore, the Receiver will invariably be owed a favour in future, and favours can be an extremely valuable commodity.
