Situation: I am sitting on a couch with a table in front of me and there is a couch with a jacket on my right.
Alternative situations: Sitting on white single couch bottom right reading a book, a picture frame is in front of me on the right wall. I am sitting on a small couch with another small couch to my left and a couch with a jacket on it to my right at 1 o'clock.
Question: Is the number of pictures that I can see while turning head odd or even?
