I think the aged p thing is not so bad if your parents are normal and you have a err, normal relationship with them. But if your parent is irrational, demanding and narcissistic, it won't be a breeze. Some helpful tips from me:
Do not refer to your daughter as "shit as a daughter" in a screaming fit on the phone on Christmas Eve.
Do not say to your daughter, when her father dies "I don't know why you're so upset. He was only your father, he was my husband."
Do not demand that your daughter, who has a six month old baby and a full time job, drop everything and come over that weekend because you don't understand the boiler and have jammed the key in the front door. Particularly if said daughter lives over three hours flying time away.
Don't use the phone as a weapon. It is a two way method of communication.
Don't say to your daughter, when she is diagnosed with a potentially serious illness, "I don't know how I'm going to cope with this."
And don't express surprise to neighbours that your daughter doesn't seem to want to see you very often, and you can't understand why...
