So as a parent it is our responsibility to set good examples to the kid. If we want to maintain their trust and respect to us, we must be a good example for them and stay true to our words and promises.
There are no other people that will correct the children and wants the best for them but only their parents. The first to correct them are their parents and they're the reflection of how they've been grown by them. Being a good example is what must be shown to them and your way of parenting will reflect when your children grow up. The hardest part is that even if you're considered a good parent but when your kid has his own way and has grown up already as a man or woman, they have their way and free will of how they do it on their own.
