To all personnel, past and present, corporeal and otherwise:

The quarterly audit is complete. Revenue continues to accrue in units we no longer recognize. The filing cabinets have begun to hum at frequencies consistent with contentment. We advise against opening Drawer 7-J before the spring equinox.

The moss is not a problem. The moss has never been a problem. The moss is the most productive member of staff.
