I find the response of Tessa101's daughter rather extreme. Mind you, the problem with a text, or a Gransnet posting, is that you cannot tell the tone it is said in. Was it said in a jokey tone or an angry tone?
I live in a mobile not spot so texting plays very little part in my life, but I can see DD saying something like this to me - and in her case I would know it was a jokey response.
Mind you we do not know the tone of Tessa's voice when she spoke to her daughter. Was it condemnatory or puzzled or apologetic? My DM thought I over-thought the upbringing of my children and said so, in a kind and puzzled tone. But it was none other than I expected, since I had decided, long before I had children, that if I ever had any I would bring them up very differently to the way I was brought up. I never took offence but I just didn't discuss with her subjects where I knew my decisions were beyond her comprehension.
I assume that we all love our children and they love us, but why do so many families spend so much time taking umbrage at what other members say and do?
