There a different thing how do the parents will let their children grow up that's the reason there's guidance barely needed to upon growing up by the child and seeing that this kind of thing is normal in playing gambling they think it is just okay that's the reason why some of them getting addicted because it is normal thing to them because they see already in their parents activity, if you are responsible parent still it is good to let them know your child what is wrong and right so they prevent getting the same scenario as you that part of gambling habit.
Relationships can be so overrated and so disappointing - sometime parent don't know how to treat their children.
Most of the kids dont make friends with their parents. And Parents are busy in their routine. So they ignore them - that is how the circle moves.
What happens is that when it comes to almost any knowledge we depend on receiving formal instruction about what it is expected out of us and what it is the right way to do things, when it comes to relationships we simply expect that people will learn on their own without any guidance at all, and while some do there are many people that do not, this is what causes parents to be almost strangers to their kids and eventually have almost no influence when it comes to keeping them away from gambling.
