Complete Bafflement

Why do some people do the things they do? Why do they adopt particular attitudes and hold certain opinions? What is it within them that makes them see some things as clearly as the hand in front of their face yet renders them unbelievably oblivious to what's surely obvious and essential? I am completely filled with bafflement at a string of recent developments in my emotional life. I hope coming events bring at least a degree of enlightenment and with it, oddly, reassurance.
