Yes Art, I feel like saying that sometimes. Being Diabetic I do get Family saying to me 'You're not suppose to be eating that', so I find something which they are not suppose to do and reply to same back to them.

Do you ever feel like saying that to anyone?
You know, the 'do gooder' types who think they know best!
Lately, l made a meal for a friend of mine and made apple and blackberry crumble for pudding. I offered custard, ice cream or cream to pour on it and he chose cream. As l poured cream on mine, he remarked, 'Do you think you eat too much cream?'
I went mad! A guest in my home, eating lovely food l had prepared and then had the cheek to make that remark!
Another friend seems to assume, l take a lot of salt and he has never seen me eat! He started discussing it with me and has now sent me podcasts of radio programmes about salt in processed food. I never eat processed food, l make everything from scratch. I don't even have sugar in tea or on anything!
Now l know how smokers, drinkers or even cross dressers feel!
So l ask. Do you get unwanted, unasked for advice from people and feel like saying........ Oh Mind Your Own Business!

unless it was a member of my immediate family, or someone had asked for my advice, i would never offer it in a real life situation, although of course i say what i think on forums, hopefully not too rudely

You know what Arty, if I were in your shoes, after you had gone to so much trouble, would tell them to Foxtrot Oscar, Really I would.
They are not worth your time & attention.

The politer way of saying exactly the same thing is: 'Procreate elswhere'.
