The problem with trying to break into the apartment of the Postmaster General... is that once you've done it you're home and dry. Well, if you're Moist von Lipwig, you are at least 'home'.
There's no avoiding it... life since he wasn't hung for being Albert Spangler had had its moments. (See [[''Going Postal]]'') Not all of them especially pleasant moments, but most definitely MOMENTS! Now... especially when Adora was away rescuing Golems, and the clacks clacked away efficiently and even the night mail ran nightly... it just wasn't the same.
Moist might not yet be willing to admit it, but he's bored. Not quite to the point of welcoming a meeting with the Patrician but almost.
