What exactly is it that you think parents are supposed to teach their children?
I have seen idiots saying teachers should teach toileting, toothbrushing, dressing/undressing, healthy eating, manners, discipline and so many other things.
Other than a bedtime routine, I think lazy parents seem to believe teachers should do all the jobs and just leave parents with the odd pick up from outside a club.
I get that they teach a load of rubbish in schools.
My opinion of schools and teachers is so low I electively home educated both my children as I wanted them to thrive. (they did/do)
But really, parent your own child or don't have children.
It's not a teachers job to parent your child.
They probably do teach some of that stuff but you don't even pay attention to what children learn, you just assume everything is fine as long as you don't have to make any effort whatsoever.
Bet you'll pull a surprised Pikachu face if your kids don't do well in their GCSEs too.
If you don't know how to change a lightbulb, look it up on YouTube, practise it a few times then TEACH YOUR CHILD this very basic skill.
Stop leaving your children ignorant while you are waiting for other people to do your job.
Children deserve parents who can be bothered to put down their mobile phone long enough to teach them how to cook pasta, or use kitchen appliances, change a lightbulb, manage finances or whatever it is they need to do for life skills.
Children deserve parents who will learn those skills if they don't have them just so they can pass them on to their child.
It is YOUR FAULT if your child doesn't have those skills.
What is the point of you if you aren't bringing them up to cope in a normal everyday situation like reading a meter or setting up a direct debit?
This attitude of offloading all your responsibilities onto everyone else makes me really angry.
I pity the children of parents who think like you OP.
