They were sitting at the kitchenette table, arm wrestling.
Hanging out and being brothers.
A nice easy, relaxing day.
Dean was currently winning when a loud crashing noise from outside caught Sam off guard.
Without thinking Dean smacked Sam's arm on the table, the sickening crack of Sam's wrist bone so evident it made Dean cringe.
He looked up to see Sam go stark white, and he knew instantly that he had broken it.
Dean didn't have time to apologize as he grabbed the keys, and Sam, and was out the door.
Another typical Winchester day.
So much for easy.
