To my surprise, I managed to extract the new TV from the car, move it into the house, unpack it from its e-NOR-mous flat box with internal styrofoam, and set it up — all by myself. I did not believe my arms were long enough, and the instructions clearly show the lifting and manipulating tasks done by two people, but everything turned out okay and I did not strain my back.
For an encore, I rolled up the parlour carpet (another cat attack) and hauled it out to the garage for the cleaners.
