y as a function of x

if someone was to graph my life out 
i believe a definitive derivative function 
of my life would be a bird: a red one 
that taps at my window and lives on 
my shoulder. at the other end a blue 
it will soon take flight and cover my 
arm - a trajectory of cancellation in 
my ever expanding mind and body & 
what i've learned to explain as an identity 
squared away nicely into my existence
