I heard this a lot growing up, I don't remember who by, so it could have been a common phrase but equally could have been isolated.
It would not have been said to me because I never spoke up as a child and definitely wouldn't have asked for something.
Does anyone remember it?
Also, is this not a really odd way to act towards a child? Nowadays we encourage communication but this has a tinge of 'children should be seen and not heard about it'
