That is why we rarely see most gamblers telling us that they're in the right condition or the actual condition of being in control. Because as you observe those that are actually who have lost already, they're the ones that will tell good things about themselves but trying to avoid the conversation that they're no longer okay. They can't control themselves anymore and they're hyper and hyping themselves just for them to put the conversation into other topic and not focusing on them.
Many gamblers try to hide the real conditions of the losses, but we will eventually find out after we observe his awkward and uninspired behavior. But we shouldn't pressure him to question his condition because he's trying to recover from gambling losses, it's better to invite him to relax in a cafe or other place to relieve stress.
