You know, some people that you would consider simpletons are intensely happy due to their attitude in life and I for one am always interested in those people. People with a drive to explore the world or to make their loved ones happy. To me you sound pretty ignorant if you claim that you can peel back a layer on something as complex as a human mind and then claim to find it empty.
If you walk the footsteps of a stranger, you will learn the things you never knew you never knew. Though you seem to feel like you know what you don't know. And I'd consider that a somewhat boring attitude, although I'd be interested in how you came to feel that way.
