For most of my childhood exams (till a teen), I had the same pediatrician. Until I was about 12, he shared practice with a female doctor in a ranch-style home that she converted into offices. The bedrooms were used as exam rooms, but the style of home had oblong windows placed very high on the wall - maybe 4.5 feet above the floor - and the windows themselves were maybe 2 feet high and 6 to 8 feet long. They were so high up in the room, that no one could have seen in from the outside. That never worried me then, the worst part of going there was being weighed and measured in my undies in the very public hallway.
When I was 12 my pediatrician bought a one-story home across town and converted it into his own office space. It was a different style house and I think the waiting room and reception area had been an attached one-car garage. The exam rooms were in the rest of the home, which had large windows throughout - maybe 3 feet wide and 5 feet high - that were mounted halfway between the floor and ceiling. In at least two rooms, the exam table was placed in front of the window, probably because it was the longest wall in the room. One of these exam rooms (in which I always seemed to be placed) looked right out onto the front yard and side walk, which was maybe 20 feet to the street.
There were blinds on the windows but they were always turned open. One day in middle school I walked to the doc's office for the mandatory school physical and some classmates of mine were walking in the general direction of his office, since they lived in that part of town. I avoided them seeing me walk that way, and hoped that the girl who lived just across the street did not see me go in.
Of course, I was taken to the exam room in the front by the nurse and ordered to strip off everything by my undies. She came back to weigh and measure me (thankfully there was a scale in the room) and then had me sit on the exam table to wait for the doc. Whether or not anyone could have seen my bare back from the street I do not know, but thinking of how he conducted the exam, I turned and closed the blinds.
When the doc entered he asked me a few questions and listened to my chest, but then said "I wonder why these are closed?" and reached over and opened them up. That was immediately followed by having me lay down, which included a genital inspection. Of course, I felt like I was on display for the whole world!
