The Frozen Kitchen Clock

Dear Delyara, The old iron radiator in my hallway has a specific three-note metal clicking sound it makes right before the heat actually hits the pipes. It sounds exactly like someone tapping a heavy coin against the skirting board. Click. Click. Clack. After three years in this flat, that tiny mechanical sequence has become my brain's cue to loosen my shoulders. We train ourselves to love the strangest noises if they promise comfort.
