Has anyone heard the song Monsters by Imagine Dragons? That song is just like Sam Whinchester.

While you're hunting-

Sam:
Sam was protective and made you stick close to him. Although, sometimes, he let you go off on your own. ONLY, if there was no other choice.

Dean:
Dean didn't want you on your own. He didn't want a repeat of Jo. He was sorta scared that if you got hurt, your parents would kill him.

When they return home from a hunt-

Sam:
You stayed up all night if you had too. Just waiting for him to come back. When he finally did you two hugged and kissed. A lot. You snuggled on the couch and watched movies.

Dean:
You grabbed him in a huge hug and snuggled with him. He would be telling you about anything funny that happened.
