You can never talk to a person to play gambling just for fun only and no hidden agenda if money is naturally involved in it, They will always tend to target that desire to win for money, You can not blame them that is the human emotion and playing with human emotions sometimes cover our judgment and decisions making, That is up to a person on what kind of approach he will do in playing gambling, But I really think you can give advise when you had a relationship with him or her,
True, I think gamblers think first it is for fun but once they get into the game they lost it, they forget what their goal is once greed take over them. Also gambling involves money and once money is involve that means the person is into the profit as well, gamblers just have to know when to stop so that they will not become addicted.
Different gamblers have different goals when they gamble. Most of them gamble for money and profit while some are gambling just for fun but you can't blame them if they have a different perspective when regards to gambling. Its their own decision into what is their main purpose why they gamble. What can I say only is that they must be ready in every risk or consequences they might face while they are gambling. Excessive gambling can lead to addiction.
