Situation: I am facing the window while having no bookshelves in my six o'clock direction and there is a chair in my three o'clock direction.
Alternative situations: Taking a minute to appreciate the weather outside the window in front of me before I sit on the chair on my right. I am casually standing facing the window on the left checking out people outside as they walk by.
Question: How many bookshelves are against the wall behind me?
