What if you have a kid on the house and you're currently making bets online and you accidentally have a phone call or what so ever thing you might do on that time and suddenly the kid mistook it for some fancy game and make bets on his/her own, would you be upset and get angry to the kid? Or would you rather trust a child's play on this scenario?
No, I won't get angry, in the first place, it's the parent's obligation to make sure that, your child behave properly and not to meddle, I will just advise the child to not do it again and, and ask him to always ask before he meddles on anyone's business.
I don't want him at a young age to know gambling, because we know children are easily attracted, to games.
