Contrary to his attitude about the whole being human thing Gabriel didn't actually hate the notion of the human experience. He'd lived it, in a way, for much longer than the humans he knew. But he'd lived it as an archangel which meant there were certain daily needs and routines he'd always been able to avoid. Eating, drinking, sleeping. Everything had always been done because it was something he wanted to do, not something he had to do. Then there were the smaller tasks. Brushing his teeth, showering, changing his clothes and, specifically at the moment, laundry. Humans spent so much time just tending to their quality of life. No wonder they were so stressed.
It wasn't just the menial tasks, though. It was the absence of his true self. Not just the wings, but his whole.. essence. His grace was unique to him in the same way that a soul was unique to a human. And without it.. Well coping with a few billion years of existence without the tools to properly adjust to that knowledge was overwhelming. And exhausting. And would have been a lot easier if he didn't have to do stupid things like laundry.
Without Sam he wasn't sure if he could have adjusted quite as much as he had. Sam was... Probably more than he had earned, frankly. He cared and he listened. Most of the time Gabriel was just waiting for the other shoe to drop. No one ever put up with him indefinitely but he'd take as much as he could get.
Which was why he could at least muster a tired smirk when he finally hauled his admittedly kind of small load of clothing to the laundry room and found Sam there as promised. It wasn't like he'd amassed much in the way of clothing up to now. He'd never needed actual changes, after all.
"Honest answer - how long could I actually wear clothes without having to wash them if this thing goes on for a while?"
