Ever look in the mirror and one of those WTF moments?  
Umm… well, yeah.  Me, either…
Let’s throw out the literal mirror here and think about your life.  I wonder how I got to be “that guy.”  I don’t have a problem being that guy, and he isn’t even that bad a guy to be.  But how did I get here?  I don’t remember getting here.  I remember things that happened between then and now, but not how that got me here.
Does that make sense?
I guess life just tends to happen and occasionally you have to reassess and accept where you are.  Or is it who you are?  But I don’t for the life of me know the how or why.
