"Don't think about it", he says simply - four short words after she tells him how guilty she is, how disappointed she is at herself, how she wishes it was all over. 

She knows he's trying to make her feel better. He's said everything he needs to say and she's heard everything she needs to hear and she knows the heart is just a bloody motor, the head is meant to drive... but sometimes that's not enough. 

"Don't think about it", he says. He's trying to be kind, and she thanks him for it. But she knows she should think about it. She should keep it in her mind. She should always remember. 

She shouldn't hurt people who've done nothing to deserve it.
