We Know Not

 We know not what private inner worlds and experiences lie beneath the exterior of those we know and are surrounded by in our lives.  

Goodness, this is certainly true for my own life and experience.  There are things about my own private inner world and experiences that others know nothing of.  But then I am aware that this is not entirely true.  

And those who share parts of our inner experiences are the very ones who would not question our sanity.
