SIL used to do all sorts of runing for her soon-to-be-ex in-laws... when she had her break down, one of the things taht she was told to do is to stop catering hand & foot to the in-laws. for 30-some years (!!!), she did an awful lot for them - clean their house, shovel their sidewalks, go on food/booze runs, bring htem food in winter, etc.
