Situation: I am sitting on the couch with no backpack on top and facing the table with a few chairs.
Alternative situations: Just got up from a couch behind me, I am moving a chair closer to the table, while there is a bag on a chair in my two o'clock direction. Completing my homework in a chair at the table and I toss a ball up paper in the trash can on the left.
Question: How many seat cushions does the couch in front of me have?
