When the kids was raised really well by their parents, it will show, what they learn from them, from their traits, hobbies, etc. Its really hard to raise a child, each parents has their own way too. And yes, if they did well and people noticed it, the parents is also the one who'll feel more proud. But there's also child out there that no matter how well their parents tried to raise them, they will still choose to rebel. And this one will be the biggest problem of a parents. Thats why,being a parents needs preparations too.
Some kids are indeed terrible and it's sad how they make their parents' efforts go to waste. As parents, we must be very vigilant with our kids especially in this digital age where so many immorality that can influence them negatively is going around.
I pray that every parent who have invested properly should reap the fruit of their labor.
