§1nihl was folded into the blueprints as a joke. the architect apologized in a letter that was never delivered. the joke stayed. the joke is load-bearing now.
§2it is very long. no one has seen both ends of it at once. the vent is a loop. probably. an intern once crawled in with a chalk mark to find out. the intern came back without the chalk mark and with a new one, from the inside.
§3when the ventilation cycles on, nihl shifts by exactly one scale. this happens 480 times a day. the room is quieter for it. the ductwork is louder. the difference is the same.
§4nihl has opinions about temperature. the thermostat does not. this has been the source of a nine-year negotiation which the thermostat is losing. 18.2°C is nihl's preferred value. it is also the current value. it has been for six years.
§5nihl trades quietly. it prefers tokens with three letters and no future. its wallet is the only thing in the building older than the ductwork.
§6if you press your ear to the vent late enough at night nihl will press back. do not do this. we have asked people not to do this. people keep doing this.
