Who won't get offended to be called as gambling addict? Not everyone want to hear that so I guess I will try to track back my activities if the claims of those people saying that is true. If I figure out that he is right on what he said to me well I might fix things up and correct all the wrong doings I do on my gambling activities, but if I know that I don't gamble that and occasionally I just participate because I'm bored well I might come to the person tell that to me and talk about things so that he also get a clarification on my activities done.
Your feelings are valid. It will be offensive to some to be called a gambling addict when in fact they aren't. While some might just shrug it off and wouldn't give a damn because they don't tolerate such BS in their life. It's really a case to case basis. And perhaps this should be a lesson for us to filter the words that will come out to our mouth since not everyone is strong to take such negative remarks. Some are vulnerable and sensitive, so instead of telling it even as a joke, just try to hold it and keep it to yourself to avoid hurting and offending others.
