Kids should be taught “sorry” by example by their parents cause more likely than not… those parents may be the only positive example you could possibly get on when “sorry” could be appropriately used.
You know the only time I ever heard sorry in my younger years? The elementary school bullies; who were saying sorry cause they had to, but were not actually sorry for what they did and were only going to continue the bullying they were doing once the teacher’s back was turned again.
And to this day there are times where now I can’t tell if I should say sorry, cause the times I think an adult should say sorry, they never do; the only time they say sorry is when they want to either escape the hive of bees they’ve enraged in a person or when they want to guilt someone for justified reactions.
Say sorry to your children when you make a mistake, or they may never say sorry to you in return when they make a mistake in their later years cause they don’t properly know how, as the only thing they’ve seen is stubborn superiority pride.
