Family past incidents will always play an effect in the minds of those who may want to consider gambling since they could have seen some family members that gambling has had an adverse effect on before and hence use that in their own decision making when it comes to gambling.
When family members do hide such incidents for the reason of shame or not encouraging then new generation of people get fail to make use of those incidents. I am saying this because my father hides his many frustrating gambling incidents. If he would have shared then that might have given me a change.
