Why didn’t I know that?

March 15, 2020 (Chapter 18 Problem solving in my book)

Last week, I got some new living room furniture. Today my son came over to my apartment to take my old rocking chair out of my apartment so that he could get rid of it for me. He was looking at my new reclining sofa. He said, “oh, you have a usb outlet to charge your cell phone.” I had no idea that I had that! When the furniture was delivered and assembled, they never told me about that. I was pretty clueless. I did see some lights on the side of the sofa but I had no idea what it was. I told my son that I had no idea that was what was near the lights. I thanked him for telling me.
