So I trundle downstairs this morning to find a spotless kitchen floor, but kitchen cupboards stained with brown. Husbad had dropped a cup of coffee. He had the brains to clean the floor before the Wrath of Wife descended on him, but even with all his academic and professional brilliance at his power, it simply did not occur to him that the coffee might have landed anywhere other than on the floor, and his eyes failed to register the streaky cupboards.
When I write, my eyes fail to register the word 'just', and I have to go through all my manuscripts using find and replace to cut the 'justs' down to a reasonable amount. I've found it occurring three or four times in a single sentence. I also don't always notice repeated words in my own writing - a much harder problem to fix as I can't use find and replace on every possible word I might have used (can I?).
Is there anything your eyes or brain simply refuse to register, either in your writing or in the world around you?
