Situation: I am sitting on a chair facing the square table I am at while there is a long table behind me and there is no other chair on the same side of the same table with me.
Alternative situations: I sat at the table to study and there was a chair to my right. After sweeping the floor near the long table behind me and pouring some hand sanitizer from a dispenser in my four o'clock direction, I spotting the bread crumbs under the table in front of me.
Question: Is the table behind me long or short in length?
