Just a one shot based off something I saw on tumblr. Hope you guys like it!

It was a good day. Sam was finally out of his latest mood that had occupied him for over a week, which started as soon as I informed the boys we were moving again. When we settled into a diner that evening, he actually cracked a smile, and Dean being the older brother he is, immediately jumped on the opportunity to turn his smile into a laugh. By the time we headed back to the musky motel room, the boys were wiped. They both settled into their twin sized beds while John turned out the light. He turned to leave the room when he heard Sam. "Goodnight Daddy." He stopped at the door, tilted his head down with a small smile playing at his lips and replied "You too, son." He turned to leave again when a slightly older voice pitched in, his tone hopeful. He said the same thing; the same exact words Sammy had, no originality, "Goodnight Daddy." He needs to grow up already. "You're too old to call me that." John said, hoping to get the boy to mature. Dean's voice piped up again, devoid of his earlier hope, "Goodnight sir."
