Interest in gambling spreads quite quickly in groups of friends. Everyone strives to brag about their successes, to show how successful they are. But no one likes to talk about their expenses. I've seen those who lost a lot but kept it a secret. And let these people earn a lot, but later spending on gambling seriously ruined their lives.
I believe that you should try not to gamble periodically, because periodicity always makes any activity a habit. And unfortunately, there is someone with a weak character in every party.
It depends on who it is; I've even seen people bragging about how much they lost in their last gambling session. Yeah, there are people who're that dumb and feel like it's something to brag about. But you're right; the majority doesn't reveal how much or how frequently they lose but only presents their winnings. Gambling periodically is fine if you're aware of how much you're spending.
I understand - its hard. Seeing a friend spiral is hard, but I believe in balance. When done safely, gambling may be fun. Rather than cutting off something people appreciate, establish lines when necessary. If I can restrict my gambling, excellent, but I must remain watchful. Setting boundaries, especially for vulnerable people, is whats needed, not quitting. Instead of stopping the activity, we should change how we use it in delicate situations.
Helping our friend is vital. Professional help and a supportive environment are essential. Gamble properly without triggering or enabling his compulsive behavior. A delicate balance between personal freedom and collective duty is needed.
It is certainly not the most pleasant thing to see. Moreover, there isn't any standard or designated approach on how to handle something like this because everyone is different and their reactions are too.
