I don't look to find other peoples drama, its hardly entertaining to me but if I happen to be in a place to witness it by all means sometimes it can be pretty entertaining and like you said a good reminder of why you don't involve yourself in it. Drama is more often than not petty so why even bother, your energies should be focused on constructive and meaningful activities.

A lot of people insight drama out of boredom or to create a quandary for themselves as an excuse to not progress out of fear of the unknown. Rather stifle your growth than grow.

I too hope the next generations learn from our silly mistakes even just a few more than this generation.
