Those that keep their gambling habit a secret is it that they're not proud of what they are doing?.
Let me just go straight to the point of your question. People who keep their gambling habit a secret, are those that are chronic gamblers probably they might have sold most of there belonging and render themselves useless with Dept all over, and they have been given warning never to be seen in a gambling hall or anywhere close to gambling casino. And in pursuit of to abide on that law, they hide while gambling. They don't do it for anybody or there friends, but because of the commitment they have made.
With there family.
This is an answer that is actually not very correct if you say that those who keep their gambling activities secret are chronic gamblers, how can gambler who keeps their gambling activities secret is chronic gambler?
Maybe they sold some valuables and have also lost lot of things which makes them like useless gamblers but this is their problem with themselves not with anyone else and there is no reason to hide all this from the public.
That was mistake they made and I sure what they did was actually known by many people including all family members, selling most of their valuables to be able to gamble clearly would be very visible so it had nothing to do with keeping it secret.
Truth is that gambling activities are kept secret because of the desire to remain anonymous for several basic reasons, one of which is to avoid bad things such as extortion or theft when winning big.
Apart from that, it can also be said that not everyone perspective on gambling is good because in social life gambling is still considered bad activity.
There are various reasons that can actually explain this context and not all of them will be related to some nonsense.
