Well, that all depends on how old are you?
(edit: nm it says you're 30 in your profile)

If you really want to be pessimistic about it, study a bit of world history, ancient and modern, and see how it's like a bad daytime soap opera -- different people, different places, different circumstances, same f'ing story, with the same f'ing "surprise ending that nobody could see coming."

Ask yourself whether you can honestly blame the individuals involved in each of these circumstances, or perhaps they're merely indicative of a systemic fault that humans are unable to escape from?
