Situation: I am sitting on the chair and the whiteboard is behind me.
Alternative situations: I sit in the conference room on my rolling chair, crumple up the paper with my meeting notes, and try to throw the ball into the trash can at my 1 o'clock direction. I am sitting on a chair that is slightly angled in the room reading a newspaper as I face the table in front of me.
Question: Which direction should I go if I want to throw litter?
