What have you been the most naive about?

People.  I know that all people are different... but I always thought that deep down, all people were good.  We all get the same warnings: don't go anywhere with strangers... don't take candy from strangers... don't talk to strangers...  Our parents warn us for good reason.  I could never imagine hurting a child.... yet there are people out there that do it.  Sure, I have my issues with anger, but I would never kill someone.... yet people do.  That totally baffles me! 

I've loved scary movies for as long as I can remember... I love the way your adrenaline starts pumping as you're trying to escape the bad guy...  But I always knew that it wasn't real.  I watched the news.... and although i know it IS real... I file it away in the back of my head with the rest of the scary movies... it just doesn't seem possible.  It breaks my heart...
