for good

i've heard it said
that people come into our lives for a reason
bringing something we must learn
and we are led
to those who help us most to grow
if we let them
and we help them in return

well, i don't know if i believe that's true
but i know i'm who i am today
because i knew you...

who can say if i've been changed for the better?
but because i knew you
i have been changed for good
