Here's the science bit... the left side of the brain is where visuals and imaginative ideas are constructed and so....

Is someone being misleading

Telling tales Oh So deceiving?

With every word they utter

There just ain't 

No believing

Still searching for the truth

But not a single trace

One thing  that you must do

Look straight 

Into

Their face

As soon as you've asked 

Your question

Follow the direction

Of their eyes

If your suspect looks

To the left

You've probably

Been told a lie

Or if you need a new idea

And  feeling

All bereft

You might get

To change career

It just takes a look

To the left
