My Dear Fellow,
You can hardly expect me to sympathise with your situation, as I paid Phoebe good money to perform said task (namely, cleaning your room). The state of disorder is an insult to mankind, and the stench of the rotting banana peels gravitates across the hall to my chambers, preventing sleep when it is most needed. The best advice I can offer is to keep your room in some semblance of an order, or you will face both Phoebe and myself the next time a cleaning is due.
P.S. The feather pistol is called a “duster”. You ought to pop into the store and see if they have one available for purchase. I would be happy to show you how to use it.
