Situation: I am sitting on a chair with one leg on the desk in front of me and counting there are some desks in front of me.
Alternative situations: While sitting in the chair at the head table in front of the desks with partitions, I am reaching for my backpack on the left side of the desk. Studying at the head desk in front of the desks with cubbies.
Question: How many desks are exactly in front of me?
