Ah, but there are “universal laws” that occur, especially when one taunts those laws.
Mentioning that a piece of equipment is still working spurs those laws into sending gremlins out to punish you.
It’s true that the Universe is hostile. But it is also basically indifferent.
I shall scoff at your superstitions, and speak truth to power as I choose. Knock wood.
Taunting universal laws doesn’t bother the Universe. The results just happen. It’s Fate that thinks it’s great fun to put in a twist. All machines break down, and the universe won’t send anything to break your washing machine down just because you claim it’s working. However, Fate will try to make sure it breaks down right after you get the most humiliating stain on one of your articles of clothing.
