She made a mistake, however, when she accused Slim of being an alcoholic after she saw his pickup parked in front of the town's only bar one afternoon.  She emphatically told Slim, in front of the entire congregation, that everyone seeing it there would know exactly what he was doing. 

Slim, a man of few words, stared at her for a moment and just turned and walked away.  He didn't explain, defend, or deny.  He said nothing.  Later that evening, Slim quietly parked his pickup in front of Bertha's  house, walked home, and left it there all night.
