Well I’d definitely notice and judge you for it I’m afraid. It’s about table manners. Children with special needs I can make an exception for, but there’s no excuse for adults - “it isn’t comfortable for me” is a bit of a pathetic excuse.
Even leaving aside the clear othering of children with SN, why is my own comfort, when eating my own meal, less important than your self-righteousness as to what you prefer being the only ‘correct’ way? You remind me of those boorish sorts who will inform somebody with an unusual name that they are pronouncing or spelling their own name wrongly and will insist on saying/spelling it the way that they prefer it and thus deem 'correct'.
You're presumably an adult and as such, regardless of how you ate as a child, as an adult it's encumbent on you to have the basic knowledge and application of such basic etiquette of how to hold cutlery!
Fgs, children in nursery are taught this!
I will be too polite to specifically point out basic knowledge of correct word usage that ‘should have been taught in school’, but why does it actually matter to you? Think about it: don’t just say “But it’s etiquette” without actually considering why it matters or why one person’s way is correct and another person’s renders them unable to be considered a proper adult?
Caring about and abusing people for holding their cutlery the opposite way from how you do is just another form of controlling behaviour. If you will play your face and start condemning people, accusing them of being like children, having no idea of how to eat in public etc. – I presume you also approach and put in their place people you see wearing socks with sandals or ‘last season’s’ colours; maybe anybody using a mobility scooter or a walking frame is challenged to justify to your own personal satisfaction that they are indeed disabled enough to need it and not just being ‘lazy’; do you criticise married women who work outside the home, because ‘tradition’ and ‘etiquette’ suggests that they are ‘wrong’ to do so – and assume that they are only living their own lives in the way that best suits them to upset and offend YOU?
Good manners are one thing, but etiquette is mainly a way for the rich, powerful, influential and/or self-important in society to go around kicking and bullying others who do things differently from them or have different opinions. Different, I said; not wrong.
We get this on the threads about addressed envelopes, where a poster is upset and feels completely overlooked as a person in her own right, because she receives birthday cards addressed to Mrs John Smith when her own name is Emily Jones. There will always be somebody coming on to tell her that she is wrong to be upset at this, because the sender is actually correct to address it this way. End of discussion, slap you right down – your feelings don’t matter, because they are the ‘incorrect’ ones to have, and if you’d been properly taught as a newborn, you wouldn’t be embarrassing yourself this way and proving that you cannot function acceptably as an adult in decent society.
