*mildly off-topic?*
My parents only call each other by their first names only like... fifty percent of the time? XD My dad hardly ever calls Mom by her first name, unless he's trying to get her attention. And Mom only calls Dad by his first name if she's calling him from across the room (or house). The rest of the time it's 'honey' or 'dear, which... now that I've noticed it, I cannot imagine doing with my spouse (should I have one someday). XD;
