First, human beings are notorious for not being able to see themselves objectively.
Secondly, I'm not like most men. I know this to be true because in my dealings with other men throughout my life I've often said, "What the heck were you thinking? I can't believe you did that." Only to find out that he's unable to explain his decision making process to me in a way that makes sense.
Besides, I only know how I act in relationships. I have no idea how most other men act. Like I said, don't date 'em, haven't spent nearly as much time trying to figure 'em out.
