This is a bit mean spirited but I am writing myself a list of rules for when I am old based on the things I am struggling with regarding my own parents.
My list so far
Your kids do not care about your friends' illnesses (unless it impacts you eg your friend is dying or you are caring for them)
If you wouldn't say it to your daughter in law then don't say it to your daughter (eg judgement of parenting things)
Only offer food once, or twice max. It is not generous to offer a dozen times, just annoying.
Any others?
