The short lived profession of the person who would knock on your window to wake you up so you didn't miss your shift at the factory? AKA the “Knocker Uper”. Replaced by alarm clocks. Yes I still dream of one day becoming the artesianal Knocker Man. I bet unlike the blaring alarms of today, he had a special quality of waking one up like a bird on a window, gently waking us from our slumber and starting our day by sharing a wink and a smile. Those were the days.
