If you have that capability to control yourself and you know yourself well in terms of placing good limit with your gambling activity, the chance that you can enjoy and be discreet is possible, it's more on how you want yourself being protected from different criticism and allow things to take place while no one knows what you are doing behind your room or within your capable device to connect to any online gambling site.
Just doing it discreetly and away to anything that may cause a bad impression on you, there are many people around that will keep judging you once they learn that you have any relative engagement with gambling.
It's your take though, whether to be open or keep it as secret as possible, as it's your money to use and to take care of.
Unfortunately there are many people out there that are only looking for what they can dig out of you to talk behind your back and spread all kind of rumors against you, and it is key to identify those people as early as possible and expose nothing to them, as those people love to incite all kind of conflicts and then argue that they were doing it for your own good, which is completely ridiculous as they are treating you as if you could not decide on your own what is best for you.
Yeah, there are people who keep minding other's business and not just to focus with their own business, they will find ways to dig deep into your personal life and will try to create rumor with how you handle things, even you are not that addicted and you are just enjoying but in their mindsets they think that you are already dealing with some issue with your habits.
Keep in mind that you can escape from people who think that they are better than you, but everything is on you. What you do will reflect on how you handle the situation and how comfortable you are.
