I fancy myself perceptive, and I do still think I can see into people pretty well, but have had my pride in this regard dashed on the rocks more than once lately. I'll have a web of information/circumstances/events that seems to make sense and I'll interact with it in accordance with that sense that I have made of it from my subjective, distorted view; then a new strand is introduced (or, I should say, I am smashed on the head with it - usually it has been there all along but I somehow have not perceived it), it instantly and thoroughly transforms my understanding of the web, and I shake my fist at the (to me new) strand and shout "my kingdom for a time machine". The utterness of my wrongness - in having failed to perceive that now plain-as-day strand AND in my previous behavior - in each of these situations is more shocking to me than it should be.

I can enjoy making up for it, though.
