Breaking hearts

She has a reputation for breaking hearts.
Which is why she got pulled off of the artificial heart assembly line and put in the product testing group.
“If you’re going to break these things, we’d rather you do it in a way that helps save lives, not kill people,” said the factory managers.
The curious thing is, when she breaks a heart, analysts look over the heart and can’t find the reason why it failed.
“She had such promise,” says a factory manager. “So much potential. It’s too painful to watch her fail like this.”
And another heart is broken.
