You see balled up socks everywhere. He (thinks he) sees tampons everywhere.
He constantly drops spare change and doesn’t pick it up. You implement a strict Finders Keepers policy and can now afford weekly Wilensky Specials.
You drag your feet for hours re: dinner prep, yielding minimal to zero results. He gets home and has something whipped up in under 45 minutes.
He buys a new flannel top. You secretly inherit his old one, but only wear it when he’s not around to catch you.
You suspect he uses your fancy face wash sometimes. He now knows you borrow his clothes without asking, so things are basically even.
