A dozen bottles and nothing else? The bare rack is what gets me. No condiments, no leftovers, not even a sad jar of pickles. That fridge must echo when you open it. I can't imagine the grocery trips, just coming home with a single rotisserie chicken and a mountain of hot sauce.
Honestly I used to judge empty fridges too! But my roommate lives like this and she's the happiest, most put-together person I know. Maybe there's something to just buying what you need right now?
