Empty

So here I sit, empty
because you drank me completly

I shouldn't be this sad
After all I've only changed density
And I was only here to be had
Maybe it's the lack of honesty

Because no matter what I add
I still make you mad

so you keep draining all that you can subtract
And treating me bad
how else should I react
when you keep setting me aside like a fad

And you are so exact
to give only what you subtract.
