Situation: I am sitting on a chair at the table and facing the table, while having a chair on my right within reach and the door in my ten o'clock direction.
Alternative situations: I took a seat at the head of the table and there were many other chairs in front of me. I am sitting on corner of a table with one leg on top of the table in front of me.
Question: How many chairs are on the left side of the table in front of me?
