Biting his tongue was never something Sam was known for, but especially when there was potential for his son to get hurt. Standing by the door, he shook his head as Dean swung DJ up in his arms, and carried him over to the icicles that were glistening as they dangled from the edge of the roof. He whispered something that made him laugh, but all Sam could see was the inherent danger in what they were doing.
"Alright, bud, see? You can lick-"
"Dude!" Sam had finally seen enough. "You are not teaching my kid to lick an icicle!"
Dean rolled his eyes, before hoisting DJ up on his shoulders. "Relax, Sammy. He's done it before. Hasn't hurt him. "
Sam could feel his eyes bugging out of his head.
