Situation: I am sitting on a chair by the large table where there are no more chairs on my left. There is a door on my 4 o'clock direction.
Alternative situations: I am sitting on the chair closest to the desk with a backpack and have my phone on the table in front of me. I am sitting on the chair closest to the black table on my right speaking to the person across from me.
Question: How many backpacks can I see?
