My father believed you could fix most electrical items with a screwdriver and a few creative curses. The first and only rule was to leave it plugged in. The current hitting you and your body hitting the wall would usually correct the problem and cure your ability to speak in full sentences all at once. There was probably no hope, therefore, that I would end up feeling the need to crack open an instruction manual. Luckily, I’ve found mistake making the most powerful learning tool available – every bump, bruise or scar jars my memory into providing the corresponding cuss word.
