As a pediatrician, I would routinely examine newborn babies in the hospital rooms where their mothers were recuperating from the delivery. I would always knock on a closed door to avoid any embarrassing situations.
One time, a mother answered the knock on the door with “Come in,” only for me to find her standing totally naked in front of the sink within the room (not the bathroom). She was shaving her legs and underarms with a total lack of modesty.
I quickly closed the door and told her that I would come back when she was dressed. “ Oh, that’s all right,” she replied, “You can come in now.” I did request that she at least put on a hospital gown so that I could examine her baby.
It turned out that she was from Brazil and believed that covering up was unnecessary. I remember warning my male partner about this since he was making rounds the next day.
I was never put off by mothers nursing in front of me, but I felt that it was strange and somewhat inconsiderate for anyone to be totally naked when I would walk into the room.
