Mirror On The Wall

Broken Glass and waterfalls
I really thought I made it through it all
But here it comes again
Sending out a call, like an old friend
The monster approaches
I prepare for battle
I feel my iron will begin to rattle
Disarmed and dismayed, I stare at the face
Of the figure that stands so tall
I realize it is not a monster at all
It is me I see, in the mirror on the wall
