You are absolutely right. Isn't that how it should be?
However, in many cases children are entrusted to other people or housemaids, so children spend a lot of time interacting with them. The child imitates whatever he sees in them.
At first, many parents ignored the parenting style of their children, but in the end they complained about their child's attitude which was like the attitude of a housemaid.
You know? If they are highly educated, of course they will not choose to become housemaids.
How do you see @shohana1 ?
