I think it's a bit strange when the family doesn't know, because a gambler will definitely show unusual behavior, such as their money running out quickly or other things related to money. For me personally, from there, questions started to arise, why did his money run out so quickly, for example, and that could be the start of following up on what he was actually doing. I don't think it's possible for a gambling addict not to exhibit unusual habits, especially in financial terms.
Not everyone can be open with other people even though it is their own family, if a gambling addict is a closed person then it is impossible for his family to know how financial he has so it is difficult to find out.
On the other hand, I believe not many people want to tell or show their finances because this stage is a privacy that is so guarded.
Yes, it is clear that gambling activities and addiction can be shown when someone holds a cellphone or uses a PC all the time while gambling because a gambling addict can spend a very long time using a cellphone or PC for them to play.
Indeed, in this case, not everyone can be open, but when they are still living with their parents, in fact, if the parents really care about the child's unnatural behavior, it can actually be seen under any circumstances.
Unless the parents don't really care. But indeed in this case, especially from the point of view of the parents who have indeed freed this, maybe this is one of the reasons because in this case, when we as children are adults, there will definitely be privacy, which of course must be maintained.
