Difference

Would you really know the difference if i wasn't by your side tomorrow?
would you really care?
would you take the time to find me?
you and i both know the answers to those questions
no one would know the difference if i wasn't here tomorrow
to you I'm just invisible
all the time I'm just in the background
lurking around the school
without being noticed
i have no purpose in my life
I'm useless and pathetic
and just wasting space and air
might as well just give up the fight i know i can't win
