Situation: I am facing the blackboard while sitting on a chair with two other chairs on both sides of me and a table in front of me.
Alternative situations: I am sitting head of the table facing the table, both my arms are resting on the table as I talk to the people in front of me. I got up because I am sitting at the head of the table away from the blackboard and I cannot read well.
Question: Is the amount of table I am facing odd or even?
