I guess everyone is very different opinion though, it's different if you tell your kids what the consequences are. Just ask the question to your self, did your parent teach you as well the bad side or gambling?
When I was growing up, I'm seeing my father gamble, yes he bet in front of me on horse racing. But he didn't teach me anything. Until when I grow up and take up gambling myself. So yeah he could be the influence in my life, but I never learn anything from him. It is myself who discover gambling and what it can bring to someone and so I will not tell my children about it or even shows that I'm gambling, just saying.
When I was a kid, parents, grandma and grandpa never taught me games on purpose. But, because there was not much things to do (I mean toys and etc), they taught me rules of poker, blackjack and other card games. We gambled just for fun. They never taught me to gamble to earn. I remember we even used coins to make bets. But it we gamble either to have fun, or to kill time. There was never - learn to gamble, and one day you will become rich.
Btw, just remembered that I even got a cartridge for snes with gambling game. I think there were slots, poker, blackjack and roulette. Maybe that is why I am so "different" in this topic
Maybe I've had enough gambling in my childhood and now I see no problem to stop when I feel like it is enough and not to turn addicted, as well as I dont understand whole drama between kids and addiction. Kids nowadays spend more money on loot boxes in video games, they have little interest to gambling.
P.S. found that gem
