you have also said that not everyone can control themselves and emotions in gambling, isn't that also very likely to be experienced by this couple and then they experience problems with family finances? It's basically everyone's right, but certainly hopefully they can change their point of view to be more realistic so that they can consider anything correctly.
Yes, maybe that will be experienced as time goes by. Maybe over time they will become addicted because they cannot control themselves in gambling because they may enjoy the games they play too much and forget about proper boundaries and self-control and this will also cause new problems in the family. It is true that this is their personal right or the personal right of every gambler.
That's how it should be, changing your perspective or thinking about gambling is actually not a place to make real money and gambling is a place to spend money quickly. That's the truth.
