I spent six months learning how to walk again on linoleum floors that always smelled faintly of bleach and stale instant coffee. The therapy pool at Leavenworth was where I spent most of my mornings, kicking my legs until they shook so hard I could not stand up on my own. My sister Brenda drove out to see me twice during that whole stretch. Both times she brought a single Tupperware container of dry sugar cookies and spent twenty minutes telling me about her garden or how high the grocery bills were getting down in town. She did not ask about my physical therapy schedule, and she certainly did not ask what it felt like when the left knee decided to buckle without warning.
