DH really struggles with DS19 just doesn't seem to "get him" he doesn't think he pulls his weight in the house but I disagree, he will do ANY job that you ask of him but he doesn't actively seek out jobs to do and DH thinks that he should. I've told DH to speak to DS (rather than me) and ask him to wash pots, empty bins etc but he won't he just seems to get more cross about it now to the point that when we're all in the same room together the awkward silence is terrible.
DS works F/T and DH is not his dad. DS is kind, polite, hardworking, DH is a wonderful man he just has VERY high standards that are sometimes hard to meet.
