I remember WordPerfect when it was still a DOS program. The simplicity of "this format code affects all text after it" was elegant.
And then we got Word foisted on us, with "this format code (which you have no way of viewing) affects the block of text before it" so if you accidentally delete or move that format code then you screw up a seemingly random bunch of text. And here we are.
I drive through a new area near our home everyday (in UK). Some of the manhole covers make a loud "clonk" noise when I drive over them. I avoid them because it will otherwise annoy our new neighbours. I used to live off a main road into town. There was a loose manhole cover there which drove me crazy until I managed to get the council to fix it. Probably just had stones in it making it loose.
