Situation: I am sitting on a black coach facing a bookshelf in front while there is another bookshelf on my right.
Alternative situations: I want to get a book from the bookshelf to the right side of the cabinet. I dropped my backpack on the couch behind me because it was heavy . Now I am looking at the bookshelf in front of me.
Question: Which object I sit on that is necessary to bear things like laptop when going outside?
