Decay.

I wrote so much today,
But none of it release.
All of it just adding harm,
Not bringing me to peace.
I know that whatever's said,
Will be met with mean retort.
You never can admit the wrongs,
You simply aren't that sort.
So tonight I write purely for me,
To set it on it's way.
I have to open the tap.
Retained poison means decay.
