Which Way To Go

My head has been split in two
And I don't know what to do
I have two parts inside my head
Positive force, Negative force

They don't know which side to go on
But my head needs to know
I do wish they would make up their mind
As this can be a pain in the backside

Running backwards and forwards
Like they're taking a class in aerobics
Slow down, Slow down, Slow Down
This makes me feel disorientated
