Dean loved the way Sam would suddenly flash him a smile.
He was irritated by the way Sam always knew everything.
He hated the fact Sam was taller than him.
It ate away at him that it didn't matter what he did, he would never be able to keep Sam safe.
When Sam cried, Dean found it annoying. As far as he was concerned it was a baby's way of calling for attention and not the actions of a twenty-something year old male.
He thought it was hilarious when he played a prank on Sam.
He thought Sam's puppy dog eyes were adorable.
But when Sam was going down on him with kiss-swollen lips...that was freaking awesome.
