if the enjoyment of playing outweighs whatever you would have spent that dollar on then it was worth it.
I have only played the lotto twice in my life (including this time), and each time I went to the bar and watched the numbers get drawn with everyone else, and had a hell of a fun time doing it.
I don't get people that are so fucking down on gambling at that level, its like some sort of religious fervor. The people buying multiple tickets and doing research and spending all the time in the world dreaming how the money will be spent are the schlumps. Not me.
Damn
