Bear With Me

The strangest part wasn't the size — it was what we found inside. My sister had lived in that studio for three years. I'd helped her move in, assembled her Murphy bed, watched her arrange everything just so. We joked about how cozy it was, how she'd mastered small-space living. After the funeral, I came to pack her things. The landlord mentioned the lease renewal she'd never see, how she'd complained the apartment felt smaller lately. I assumed grief talking. Then I found her journal, open to measurements she'd been taking obsessively. "16 by 18 again today. Still shrinking?" The entries went back months. I grabbed my tape measure, certain she'd been confused. Sixteen by eighteen. Exactly. I pulled out the original lease application in her careful handwriting: "Studio apartment, 20×24 feet, 480 square feet." But my tape measure didn't lie. Neither did the building plans I requested later — all showing the larger dimensions she'd believed she was renting. I stood in that 288-square-foot space, understanding something had shifted beneath her feet long before she died. The walls she'd trusted had been closing in, and no one — not even me — had believed her when the familiar became foreign.
