Superman's heart (JRT)

Superman may have a body of steel
But he has a heart of glass
Fragile and breakable
Quite easily shattered

He can brave the harshest of conditions
Weather the greatest of storms
And come out unscathed
With not a hair out of place
And not a wrinkle on his cape

But place Lois in jeopardy
And you can bring him to his knees
Threaten her life
And he'll do your bidding

She alone can control him
If she so desires
For she controls his heart
And his heart controls him

That's how it is with me
Not by any means am I Superman
But my kryptonite is the Lois' of this world
She bring me to my knees when no one else can
And she makes me cry with a broken heart
When Doomsday breaking my back
Won't even make me flinch
