Something Unrelated, Sort Of

It was smaller than I remembered. It's always smaller than you remember. Uncle Morris left me his garage—the one I'd spent summers dreaming about, watching him restore vintage motorcycles with surgical precision. Now it was mine, along with his tools, his workbenches, and the promise I'd made to Mom about finally slowing down. I paced the concrete floor, counting steps. Twenty-four feet wide, maybe forty deep. Enough space for four cars, he used to say, but Morris never owned more than his old Triumph. The rest was workshop—every inch organized, purposeful. The lawyer handed me the keys with an envelope. Inside, Morris's spidery handwriting: "The bikes are fast. Too fast for an old man. Perfect for you." I found them behind a false wall—three pristine racing machines worth more than my house. My pulse hammered as I ran my hands over chrome and leather. Everything I'd ever wanted. Then I saw the medical bills tucked beneath the seat of the Ducati. Decades of them. The same back injury that ended his racing career, that bent him into a question mark by sixty. The garage felt enormous now, stretching endlessly around me. Nine hundred sixty square feet of beautiful, terrible possibility.
