^ That would probably be the outcome, but I think we should practice this attitude not to keep secret regarding your activity daily or the daily habit. We should open to tell them if we are often gamble because if there is a time that you are beyond your limit there is someone who could give advice and talk to you. Because we know that addiction is just a silent killer, you don't know that you are addicted to gambling but you can sense that you are addicted base on your action and it could be people new you will give some advice.
In this case, honest means very important also. If we are going to help someone in addiction (that cannot control their addiction), it is true that we need to ensure he or she trusts us. Because many of them may be worried about being honest to others if they are addicted to gambling. Giving them trust, understanding, and also hope that they can get out of the addiction or at least control it slowly. Because of that, I said it was necessary to repetition in helping them. It cannot be done once twice, but continuously.
And this can easily happen if they want to be honest and aware of their own situation.
But what is rather difficult will be when they don't feel if they are addicted, they don't want to be honest both in yourself and others, and they have done a harmful thing, then we don't need to wait for them to ask us. But we need to go to them to be aware of their condition (if we really know it). And of course, this will be a little difficult because surely they will feel disturbed, angry, dislike, or offended. Because of that, we need caution and the right way for them.
