Situation: I am sitting on a chair at the big table facing the big table with two chairs in the same row on my right and the backpack is in my nine o'clock direction.
Alternative situations: I sat at the table for the meeting and there was one chair to my right. I stand from my seat as I head to the trash can further ahead pass all the chairs on my left.
Question: What type of markers do I need to write on the board I am facing?
