I often stay at the office after the staff leaves. In the winter, that means walking out of the empty building alone, into the dark night. The empty and dark parking garage echoes my footsteps. It reminds me of the poem by Thomas Gray "Elegy Written In A Country Churchyard".
The curfew tolls the knell of parting day,
The lowing herd wind slowly o'er the lea.
The plowman homeward plods his weary way
And leaves the world to darkness and to me.
