I need help in dealing with nearly constant squabbling between my elderly parents. In most every conversation they have one of them either corrects the other over something trivial in a less than respectful manner or makes a snide comment about what was said. Dad is 89 and Mom is 81 and both are in fair to good health and still living in their own home with help from me. I am to the point where I dread going over to their home. Does anyone have a suggestion?
