I have a friend who was adopted by just a mom. He does not feel any debt to his mom. When he was younger, he felt it was his duty to irritate her! (Normal kid.
)
But now he has his own kids and they are giving it all back to him.
Anyway now as an adult, he just feels he was lucky to have his mom adopt him. He is thankful. No feeling of any debt. She is just his mom is all.
And his mom feels the same. Just that she is his mom. She does not expect anything more than a biological mom would. Same Same!
So far as fathers or friends who gamble, there is NOTHING you can do except tell them you don't approve. Or suggest they go to gambler's anonymous or counseling. If they don't want to quit and prefer to keep gambling, then nothing more anyone can do.
I have a better method. I understand the math and that over the long term gambling is a losing thing.
And I have a friend who gambles. Each time he goes out to go gambling, he says he needs to stop at the bank (to get gambling money). I say to him each time, "If you can make money at gambling, then you don't need to go to the bank. Just use the money you have won in the past!"
Or I will say, "If you can make money at gambling, then all you need is $20 to start gambling, then you can use your profits from then on to continue gambling!"
That seems to have sunk in over the years. He is gambling less and less now.
