'I shan't say anything,' said Pooh at last.
'I shall just hum to myself, as if I was waiting for something.'
Humming is the sound produced by something small, fast and constant, such as the wings of a bumblebee, the needle of a sewing machine, or the ceaseless stream of faraway traffic. There can be something peaceful and comforting about humming: The song a mother sings to soothe her child. The sound of machinery working as it should. Your own content utterings when everything is good.
Yet the neverendingness of humming can be enough to drive one mad. The annoying noise of the fan which goes on and on and on. The ever-present buzz of the traffic, even when you think yourself far away from civilization. A person you don't like voicing the most imbecile of tunes, and on top of it all getting it wrong.
Even worse is the irritation when the humming has no known source. The Taos hum is a low, mystifying sound which some people claim they can hear in very silent places, particularly in Western Europe. If you know where to find these places, please hum me a line.
Mm-m mm mm mm mmmm...
Is humming good or bad?
Don't worry about it. Just hum.
