At my last job when I was asked this I said "I can't fold a fitted bed sheet."
Everyone kind of tittered and I said "It's true, every week I pull that sheet out of the dryer and think, "this is the week" and then I fail. But I keep trying every week".
I got the job.
And yes, I've watched videos, I've had people show me in person-I still can't get it right.
