Situation: I am putting away a book and there is a chair to my right and and a toolbox next to my left foot.
Alternative situations: Just found a hammer in a toolbox in my 10 o'clock direction and fixing a bookshelf in front of me now, while there is a desk on my right that needs to be fixed as well. I am standing to the left of chair browsing for books to read on the bookshelf in front of me.
Question: Is the amount of bookshelf I am facing odd or even?
