"Sentient clothing. Pretty sure that's the plot to some anime.." he said absentmindedly as he tried not to think to much about how seven days of built up Winchester funk might smell. That was not the kind of experiment he planned to try out for himself, even if it meant having to find more clothes and wash them consistently.
"I got it. If I can't figure this out you might as well put me out of my misery. Make it quick." Part of his insistence was stubbornness, sure, but it wasn't like he didn't know how to figure out how to do simple tasks once he had a little instruction. It did help that Sam already had the settings though. He poured the detergent like he'd been told, thought a second about where to put it, but ultimately managed to start the load without blowing something up. Hooray.
"You know I think I prefer washing clothes in a river. Fewer buttons. No bleach."
