My best advice for parents of adult children is do not treat your adult children differently based on their marital status, when I lived at home and my married siblings would come to visit for Yom Tovim they would sit and relax at the table like kings but this cinderfella had to do all the shlepping from kitchen to table and back and back again , while my parents A”H would slave over the cooking of meals while the young married royalty did very very little, and if they did dare suggest to my parents that they clear the table they would be shouted down of course not!! ____ will do it, because they were married so they and their spouses were no longer suitable for clearing a table and they knew that my parents and I were overworked preparing for their visit and catering to them and the truth is they reveled in their status as royalty.
I don’t say this now to shame them I have forgiven them for everything they have done to me, I am just using this as an example of what NOT to do.
