For the last 10 days I have been immersed in the medical world. Roberto had a total replacement of his right knee, and given the state of hospitals these days, they sent him home that same afternoon. From that moment he was mine. We went home with bags of supplies – six different pills, two of them opioids, two kinds of dressings, ace bandages, compression stockings, syringes, alcohol swabs, waterproof pads, two styles of ice packs, elastic straps with the strongest Velcro I have ever met, plastic containers of various sizes and shapes, including the one for disposal of used hypodermic needles – and sheaves of instructions for patient care and an equal number of warnings about what could go wrong.
