Dislogic

Once again, I make an investment of time that I know will never be returned. That gold-diggin ex of mine wrote me wanting to get together, and I wrote back. Why did I do this? By any sane cost-benefit analysis, I should have become oblivious to her existence in July or so–the action of responding is simply not justified. I tend to consider myself a logical person, which this behavior totally defies, yet I continue to do it. Why?
