As I walked through the front door after work, Mom approached me with a written list of five things she needed help with. 1a) Dad’s printer would not work.  She was right.  I unplugged it and re-plugged it in, and it worked, but she had clicked the “Print” icon so many times that the resulting print jobs drained the ink dry.  1b) Replace the ink in Dad’s printer.  2) Dad’s gabapentin was about to run out, with no refills, so would I call the prescribing doctor to renew the prescription.  I texted the hospice nurse, who had the medicine delivered to the house.  3) Dad’s glucometer stopped working, so would I go to Walgreens or somewhere and buy him another one—suddenly, after years of not testing his blood glucose levels, he wants to start testing his blood glucose levels, at age 88.  I plugged the glucometer into my computer to recharge the battery as I wrote, and announced heroically that we would not need to buy a new one.  “It has rechargeable batteries!  Isn’t that amazing?”  4) Review the list of distributees for Sarah’s tribute book, which at 52 pages, including 12 color pages, would cost $12.25 a book to copy and bind.  We cut the list of essential persons “who would still want to have the book in 50 years” (I suggested to him that no one would still want the book, or perhaps even be alive, in 50 years) from 60 copies to 40 copies, with the reassurance we could print more, if needed.  5) Write on the calendar the coming weekend’s activities.    As Mom confronted me with the list, I asked a bit testily if I could pee first, because I had drunk too much passion-fruit-flavored ice water before leaving the office, and peeing was my first priority.  Relieved, I set about the tasks, still in my hat and tie.  Mom invited me to look in Dad’s office at how she had rearranged Dad’s power tool batteries and their chargers.  Dad had kept her awake the night before repeating suddenly anxious expressions about the lithium-ion batteries shelved in his office closet—shelved by me, already responding to his anxieties about the batteries touching each other or their chargers and starting a 1200-degree F fire that would burn the house down, shelved by me alternating the chargers and the batteries, nothing touching anything else, with the tools far away in the garage.  But he had forgotten, and had begun to panic again about lithium-ion infernos, and after midnight had sent Mom downstairs in her nightgown to redistribute the chargers and batteries more safely, so there was no chance they would touch.  My completed or in motion, I examine with some confusion the closet shelf, now bare of batteries, and looked toward Dad’s L-shaped desks to see the chargers and batteries spaced there at distances of three feet each from the other.  “Looks great, Mom.  They’re certainly not touching each other.  Nothing to worry about.”
