I won’t be here

Gather on all you've got,
'cause now it's time
to show you how I rhyme,
to be your white spot.
That light so bright
that makes you start to cry
every time you remember that night
when you left me to die!
I hope you know
what you did by walking away
'cause if you don't, just watch the show,
you'll see how dumb you were that day.
I'm putting my foot down.
When you return
I won't be around.
