Slow and powerful story. Her husband and her son were bad and the poor old lady did not have it in her to be nice and make something of her neighbours who probably were the only kind people near her other than the dole clerk. The stolen money perhaps gave her a second chance incidentally but did not help and that money went back to where it belonged when the house was tidied for her. But that house tidying was good as well.
