to the occupant: an envelope was delivered to this address and left on the floor beneath the door, at the hour you were already sitting upright, ears back, tail wrapped tight around your feet, in the posture management has come to recognize as full alert.
you did not approach it. you did not sniff the corner or bat it three inches across the floor, which is the customary first response to any new object entering the room. you sat exactly where you were and watched the gap under the door instead, which management is treating as an acknowledgment of receipt.
this is not the first envelope left at this address. it will not be the last. management notes for the record that knowing what a notice says before it is opened does not excuse an occupant from the notice, and the envelope remains on the floor, exactly where it landed, unopened. finalnotice
a written response is not required. sitting very still in front of the door has been accepted as a form of reply before, and will be accepted again.
