Just now I was rereading something where I wrote “special characteristics” and I said to myself, “Huh?” Then I realized I meant to write “spatial characteristics.”
That’s a weird and complex kind of typo to make. I do that occasionally, and it baffles me.
I get how a person could spell a word wrong, or accidentally mash the wrong keys, or use the wrong word.
But when I wrote that phrase I knew exactly what word I wanted to write, and I told my fingers to type it, and my fingers went off and did something else.
