The sad thing is that their parents are perpetuating their own mistakes on their children, even if it is a bit hypocrite they should tell their kids to do as they say and not as they do, they should try to get them out of gambling but those parents that are addicted to gambling probably do not care anymore about what the kid does or does not do, and in some cases they could even encourage that behaviour as the kids end up bringing money with them and more than anything that is what those that are addicted to gambling want.
Some case here in our country that parents who gamble was open to let their children watch them while they were playing. My mother was a card player too, she used to play cards everynoon time as a way to spend her time and I am here watching her playing, analyzing what the rules of the game was and how to play the cards. At early age of mine as I could remember I was 10-11 years old I already knew how to play cards, but what the good thing was my mother didn't really encourage me to reall engaged myself in gambling. Even though she was a card player she've been able to control herself and stop gambling, but what she didn't know that I have already learned how to gamble and now I am not really a gambler but some sort of enjoying gambling.
