The hardest thing for a gambler is their appearance and their mood after they log off or step out of the gambling platform they've played on.
Not really. May be I am blessed in this regard. No matter what happens, I have this emotionless blank face, so no one can see what's going in my mind.
I have seen gambling, jumping for joy, and bragging about the amount they won, even posting their winnings on their social media account.
I don't use social media and I like to keep things to myself, so these things out of question.
