Situation: I am wiping the board, and there is a chair on my right and two couches in my twelve o'clock direction.
Alternative situations: Hiding behind the board so that no one in the couches can see me. I get up from the couch and walk to my right, then turn 90 degrees left to face the board so I can read it.
Question: How much will I need to stretch my leg out to kick the back of the black couch in front of me?
