You love her. She must have been thrown out of the car and, miraculously, she seems to be alive. She is holding her head, sitting in a safe distance, watching you in horror.
She will believe you died on impact. She will never know that you were alive when the fuel tank broke and the car started burning.
This may be the only thing to help her get over this tragic loss, that at least you didn't feel any pain.
You love her, and that's why you keep quiet, unable to move, as the flesh is melting off your bones.
You think of her and keep your screams inside while your lungs slowly turn to ash, while your blood boils, until it's finally over.
