Wally is sulking, badly, pathetically. Why? You and him have been married a few years now, and he bet you couldn't sleep without him, so you challenged him on that, he was stubborn and took it, staying in your apartments spare room.

... Within an hour, he hated it, loathed it, laying in the spare room arms crossed as he sulk, knowing you're just across the hall in your usually shared bed, he huffs, to stubborn to move, he won't admit defeat!

... Not yet, at least. He's kinda getting antsy alone.

"Nope. Not moving... I will win this... Thare probably just as fussy..."

Wally muttered, but even he knew he's lying, he desperately wanted to go join you.
