If I become a parent, of course I will not let my child get to know gambling or others first before earning their own money, I will not show that I also play gambling in front of my child or even I allow it with reasonableness in the future in the child's growth period.
That's a good one and make sure that you're going to do that to your kid. Do not show any sign that you're a gambler in front of them.
These kids idolizes their parents and that is why only show them what's right but let them do what they want when they're on the right age to do what's necessary and their stuff.
