Dean didn't have a present.
He'd meant to get something, and then there'd been that case, and they were all - well, the three of them, to various degrees - pretty much beat up. And Dean - and Bobby, for that matter, and even Cas - were most definitely not willing to let any of them alone, not after that.
Okay, so he could have asked Castiel to get something for him.
That just didn't seem right. His girlfriend. Maybe he'd manage to get her something in the next few days or whatever.
Hell, they didn't even have proper chocolates. Then again, right now it didn't seem to matter that much.
It was just him.
He only slipped away from bed briefly, looking in downstairs to see Sarah in front of the room, and the room itself quiet. Sounded like Sammy was getting some sleep, that was god enough.
Then he slipped back under the covers, and gently let Cassie snuggle against him again. Watched her sleep, drowsing off and on himself, until she stirred and opened her eyes.
And when she did, he kissed her lightly. "Good morning." Then he cleared his throat, and resorted to Billy Joel.
Don't go changing to try and please me,
You never let me down before,
Don't imagine you're too familiar,
And I don't see you anymore.
I would not leave you in times of trouble,
We never could have come this far,
I took the good times, I'll take the bad times,
I'll take you just the way you are.
Don't go trying some new fashion,
Don't change the color of your hair,
You always have my unspoken passion,
Although I might not seem to care.
I don't want clever conversation,
I never want to work that hard,
I just want someone that I can talk to,
I want you just the way you are.
I need to know that you will always be
The same old someone that I knew,
What will it take till you believe in me,
The way that I believe in you?
I said I love you, and that's forever,
And this I promise from the heart,
I couldn't love you any better,
I love you just the way you are.
I don't want clever conversation,
I never want to work that hard,
I just want someone that I can talk to,
I want you just the way you are.
And if she bore through all of that without making him shut up? Okay, even if she did shut him up. There was another, longer kiss, and a quiet "happy birthday, Cassie."
