lyrics:

Just think of this and me 
as just a few of many things 
to lie around 
to clutter up your shelves 
And I wish you weren't worth the wait 
because there's some thing's 
I'd like to say to you...

I don't think that 
you know what 
you've been missing
Cuz I don't think that 
you know what 
you've been missing

I dare you to forget 
those marks you left 
across my neck
from those nights when we were both 
found at our best
I could make this obvious, 
and you, you could deny me
all in one breath
you could shrug me off 
your shoulders...

I don't think that 
you know what 
you've been missing
Cuz I don't think that 
you know what 
you've been missing

Hey, lush, have fun
It's the weekend
Hey, lush, have fun

Hey, lush, have fun
It's the weekend
Hey, lush, have fun

I don't think that 
you know what 
you've been missing
I don't think that 
you know what 
you've been missing

Just forget me
it's that simple
Just forget me
it's that simple
