Overindulging, overeating, over drinking, drug abusing, the latest fashion, the newest gadget and just over doing it altogether. Well I’m gonna sound harsh now, basically you are dealing with very selfish people who only cares for their own temporary kicks which they need to fill their insatiable void (just like narcissist and histrionics.) Basically, find out what they crave and deliver, deliver until there is nothing left in stock.
