Expense. I swear anyone who thinks it's an investment needs to go see a therapist because they need some help lol. And no, it's not just simple expense, it's just a sub section of that mainly expenses used to have fun and enjoy yourself. Gambling should NOT be anything more than that. Well I guess it can be, but only if you're filthy rich. If not just let it be like that lol
Therapists they need indeed, because anyone in their normal senses shouldn't consider gambling to be some form of investment where you put in money and expect something in return. From the way gambling is programmed, it's supposed to be used for entertainment purposes and not the other way around; the risk involved is too much to even try to give it a second thought.
