I will give you a true story set in the mid 1980’s. My wife and I went away for a long weekend with other friends. We did not know but a very famous TV star in a major TV show on the air at the time showed up for the weekend. He was friends with our friends. It was time to shop for food so my wife made a list and was going to the grocery store. The star said I‘ll drive you and off they went to the store. Walking around the store no one noticed him. Standing in line to pay, he noticed he was on the cover of National Enquirer, so he picks it up and pretend to read with both the cover and his face next to one another. Still no one noticed. My wife still laughs at the episode when the story is told. Some people cannot believe the very famous TV star was ignored in the store.
So Mrs. Obama is misreading the situation. Others in line were not expecting to see her and if it was her where were the Security?
Just out of curiosity, who was it ?
