Filing emotions in rooms you swear you'll clean out later.

means The mental habit of sorting experiences, feelings, or roles into separate boxes so they don't bleed into each other.

from Built from 'compartment' — a small chamber or division, borrowed from French 'compartiment,' tracing back to Latin 'com-' (together) plus 'partiri' (to divide, to share out). The word started literally, carving up ships and train cars into sealed sections, before the 20th century borrowed it for the mind: a psyche with its own bulkheads, keeping the flood in one room from reaching the rest.
