Plainsong by Kent Haruf:
She looked all around. Houses and bare trees. She slid down onto the porch in the cold, lapsing back against the chill boards of the housefront. She seemed to fade away, to drift and wander in a kind of daze of sorrow and disbelief. She sobbed a little. She stared out at the silent trees and the dark street and the houses across the street where people were moving about reasonably in the bright rooms beyond the windows, and she looked up at the movement in the trees when the wind sighed. She sat, staring out, not moving.
Later she came out of that.
