My parents have an antique, granddaughter clock that has always hung in the stairwell, between the first and second story of my childhood home. I love the sound it makes when it tick-tocks. The pendulum swings back and forth, sometimes sounding achy and arthritic. I love the reverberation in the stairwell, when the clock chimes and strikes the hour. Every now and then it will wind down, the ticking, and celebration of time passing, ceasing to exist. Sometimes it takes a while to notice the absence of the tick. An hour, maybe two, comes and goes without notice. That is when the winding happens. Whoever realizes that the clock has stopped, usually my father, turns the little knob on the face and you can hear the gears, loudly grinding backwards in protest, to start work once again.
