Nobody likes to admit they are wrong, myself included.
Yesterday, a staff member came in with a cut on his hand. "Can I have a band aid?"
As I had him rinse off his hand, I took a look at his cut.
"Sir, I don't think a band aid is going to work. I think you might need a stitch".
He returned later in the day, grinning. Seems he didn't need A stitch, he need FOUR!
