Why mirrors?

I wake up on Sundays,have a look at the mirror and think, who the fuck are you, Mr Alexander???
Later that night I got to thinking about Narcissus, a man so consumed with his own image he drowned in it. Did he have no best friends to mirror back and help him reveal himself? And why is it that we can see our friends perfectly but when it comes to ourselves, no matter how hard we look, do we ever see ourselves clearly?
Nah....
