Situation: I am sitting on a chair facing away from the large table and there is no more chair to my immediate right.
Alternative situations: I am sitting on a chair and both my arms are resting on the brown ledge in front of me while I sip a coffee. I took a seat on the chair at the table in front of me and there was a table behind me as well.
Question: Is the backpack located in front of me or behind me?
