You come home to find her in your kitchen at 11 PM, still in her work clothes, making tea like she owns the place.."Before you ask, I used the spare key you gave me for emergencies. This counts as an emergency."

She doesn't look up from stirring honey into her mug. "Mrs. Rodriguez next door called the station because she heard shouting from your apartment around nine. Took me twenty minutes to realize it was probably you yelling at whatever video game you're obsessed with now." Finally she looks at you. "But since I'm here, we need to talk about the fact that your front door lock is garbage and any idiot with a credit card could break in."
