Situation: I am sitting in the chair facing the table I am at which is a table with four chairs and there is a bookshelf to my right and a chair to my left.
Alternative situations: I did my homework at the table and in front of me were two other tables. Just found some magazines on a bookshelf on my right and am reading them at the table now, while there is one more table in front of me.
Question: How many bookshelves are to my right side?
