Swap

If I were you and you were me
How different the world would be
I'd have your sinew, skin and bone
You'd have my shoes in which to roam
I'd feel your pain and you my pleasure
Hope and woe, measure for measure.

Swap our thoughts, brick by brick
Here comes the tricky bit:
Like two knives with handles changed
Then their blades rearranged
How similar the world would be
If I were you and you were me.
