Kerplunk

People pinball's what it's called,
Bouncing off the walls,
I wish I had something to do,
But no one ever calls,
And when they do I'm there in body,
But never am in mind,
For as my eyes begin to stray,
My idle thoughts collide,
Going for another walk,
This room all filled with noise,
Pointless task though this may be...
Hold on where was I?

An over-active mind's a thing,
That leads me all astray,
And problem is I'm sick of it,
It's eating up my day!
