Afterthought

You need me
You don't think of me
When all else fades
I'm still there
Lingering
An afterthought

You know I'm there
You're content to let me be
Alone in my head
Alone in the world
Sitting
An afterthought

When the noise fades
When the lights dim
I remain
I come to mind
I'm finally useful
Waiting
An afterthought

When need arises
When you need a helping hand
When chaos reigns
You need my calm
I'm gone
Moved on
After thought.
