My neighbors seem like non human persons.

The Human Condition.
The words human condition floats about cocktail parties, book tours and galleries but it rarely is embraced with extended clarity.
Primary in my understanding of the human condition is the overwhelming factor of contradiction. If you can not forgive the contradictions you can never forgive and go on to discover more about the human condition or a specific person's human condition.

"How can he be soo smart and yet be so stupid about X?" contradiction
"How can that be a religion of peace and commit horrorific murders?" contradiction.

Love the contradiction and correct the singular problem and you may be more understanding, successful and peaceful yourself.

more later gotta go to scoo
