I come from a long line of working class people, but my mum was always very strict on table manners. We were all taught how to set a table properly too. And I'm so grateful for that!
Nowadays, people don't seem to be much bothered, and it drives me mad!
I hate to see a table set wrongly - with cutlery all over the place, and I can't bear to see a finished plate with the knife and fork just dropped down haphazardly onto it!
My son-in-law knows this, and says, 'What does it matter?' (He, and the rest of his family, never position their cutlery correctly when they've finished a meal, and, to my horror
I'm afraid that my daughter has been lax in teaching her children this.) I, however, have insisted that when the children are with us, they use accepted table manners.
Now, if we go out for a meal together, or they are having a meal at our house, I have only to cast my eyes at the children's plates, and they quickly re-position their cutlery properly. (It makes me smile!)
If there's a right way, and a wrong way, why not use the right way? (It takes no more time!)
