Situation: I am sitting on a chair and facing a table that is shaped like the letter t waiting for the meeting to start while there are no chairs in the same row as me and the door is in my nine o'clock direction.
Alternative situations: I took a seat at the table and there were no chairs to my right. I am sitting on a chair that has a t-shaped table talking on the phone.
Question: How many chairs are behind me besides the one I am sitting in?
