Dean was humming under his breath along with the tape playing as he drove down the highway. He glanced over at his brother and grinned.

"Relax, Sammy," he said. "You're gonna enjoy this, I promise."

"And you're not going to give me any clue about where we're going?" Sam asked. "That'll help me relax a lot, thanks."

( Unexpected birthday present is unexpected! )

Sam had made Dean keep his promise that they would eat at least one meal a day in an actual dining establishment while on their road trip, and he'd kept his promise by letting Dean decide where they went. He wasn't at all surprised when Dean picked a diner, and was just thankful that the place looked clean.
