Situation: I am sitting on couch with a cushion behind me and facing two sofa chairs while the pillow is on the couch I am sitting on.
Alternative situations: I am standing in front of both sofa chairs, cleaning thoroughly in the gaps. I am standing in front of the couch on the right side, left side where pillow is behind me doing jumping jacks to exercise.
Question: Is the amount of cushion behind me odd or even?
