Situation: Standing in between a group of desks and a bookshelf while facing another bookshelf.
Alternative situations: I am walking between a bookshelf and the table on the left and headed to the bookshelf in front of me to look for a book about unicorns. I am standing in middle o bookshelf to my right, walking towards the bookshelf in front of me find a book to read.
Question: Is the amount of bookshelves I am facing odd or even?
