Looks like the father knows the consequences of his son's action and he just wants to guide him no matter what the scenario is, we don't appreciate this kind of love from our parents until they are no longer here with us and by that time we realize that no one has ever been truthful to us except them. He should always listen to his father and learn to be contented in his life since they all have the means to survive. If he accepted it, I'm sure it won't be the last time the son does it and until the whole family is addicted to it.
I can relate to this because I have a very religious family that strongly forbid world things such as gambling. I don’t understand too the logic of the son here on why he needs to tell the father where the money came from while he can just give him a portion of money slowly so that he will not be suspicious on the money he is holding.
It’s dumb to become honest on things that was supposed a blessings while religion is the only thing denying it. I think my father will do the same to me if he knew that I’m gambling online. Sometimes secret saves relationships like this example.
Maybe the child is too honest or can't lie when dealing with his father. But it was true that the kid could give him some of the money slowly and say that this was the result of his work in some places. Maybe with that, his father would believe him and be able to accept the money.
We cannot say it was a mistake to be honest with their parents because maybe his father's teachings, who always emphasized the meaning of honesty, were more valuable than anything so that the child was honest with his father. But no matter how we lie, especially if we lie to our parents, they will find out and they will probably be even sadder if they find out we have lied to them. And there may be more serious consequences from the lies we have committed.
