I noticed my husband avoiding using his finger yesterday when he came home from work. He was clutching a shirt, but his pointer finger was straight - which caused me to ask, “What happened to your finger?”
“My finger?” he asked.
“Yes, what happened to your finger?” I asked again, this time holding up my pointer finger.
“What?” He asked again.
“Your finger - what happened to your finger? Did you hurt your finger?”
He stared at me, looking as if I had completely lost my mind. What could I possibly be talking about now? Clearly I was on Crack and needed to be institutionalized.
“You aren’t using your finger.” I said, wiggling my pointer finger around. “You are holding your finger out like you’re trying not to use it. Did you hurt it?”
He looked at his straight finger. “Oooohhhh. I cut a big gash out of it today.”

I laughed at him. “Yes, the finger that you cut a big gash out of earlier, that you are holding weird and trying not to use. THAT’s the finger I’m talking about. Not the other nine fingers that you didn’t hurt today.”

I love when this happens to him because it happens to me all the time! Blain refers to this phenomenon with me as my “google button is stuck”. It’s that deer-in-the-headlights look I get when I can NOT figure out what the heck he is talking about, no matter how relevant and obvious the subject at hand.
I can’t think of a good “for instance” for myself because my short term memory downloads most of that stuff into the recycle bin of my brain about every 9 minutes, - which is probably why my google button gets stuck so often.
