Not the Same
Maybe it was the day. Maybe it was having gotten a full night's rest, or maybe it was because he'd been taught to be cheery again (sometimes, mind you).
Or maybe it was because that he was not the same. No, definitely not. He'd danced with death time after time, learned to hold his liquor (somewhat, mind you) and now knew that fish didn't like him (period). And after all the things he'd seen, he made a new resolution (small, mind you) to (sometimes) greet the day with a smile.
