Delurking. Everlong, you seem articulate. Why do you find it hard to read between the lines that the child CAN use a knife and fork, but doesn't like to put EFFORT into it? Why do you find it hard to ascertain that the child may well use the knife and fork appropriately enough times so that when she does become "slack" , the concerned adults in her presence would be able to discern that she is being lazy when she doesn't use them properly?
It's been stated enough times that the child isn't special needs, being left handed does not equate to eating like a caveman?
The wide eyed innocence akin to being a Southern Belle doesn't suit somebody presumably as intelligent as you. You have had loads of opportunities to follow your own standards (promoting peace within families?), but instead have chosen to be obtuse and blind to information that isn't written down literally, but can be ascertained if logic was your forte.
You've hidden a cuntish attitude behind your "liberalism". And that you haven't found a way to advise the OP (assuming that your intention really is the child instead of a need to display your superior parenting credentials) is weird.
They say that "Those who know better, do better". But as we are on here, why don't you go a step further and "resolve" this for the OP? Share your advice in non contentious manner (what with your superior concern for this child). Assuming you think that the OP is ignorant (Your posts betray you), you do know that it is nigh on impossible to to curry favour by not offering even a semblance of neutral ground in order for somebody "go your way", don't you?
I wouldn't take kindly to your assumptions about the OP (especially as they are prejudiced to suit your way of living) and I'd probably stop seeing comments from a person who continuously tries to change the narrative from "child can use knife and fork, chooses to eat like a neanderthal, jumps salty when asked to fix up" to " child can't use knife and fork, so why , at the age of ten does it matter, now?".
I rarely (or not as much as I want to) comment on "cheating" threads, because I came out of a rough situation and can still get furious, if triggered. My advice (most of the time) would be too hysterical, even if I was "right".
If you are really concerned about the OP stepchild, maybe you should ask yourself if the way you are having up the OP is "constructive" or is it just virtual, self absorbed masturbation? I mean, don't you get tired of repeating a point in the same way, repetitively, with the same result yet you expect OP to pay you any kind of mind? Change tactic, (as your concern for this child may have induced Charles Dickens stories levels of child neglect in the more feeble minded amongst us) if your aim is not solely to see words that you have typed shown on the internet (I remember how excited I was the first time I saw words of mine in an internet forum)!
