Situation: I am sitting on an office chair and there is a trash can on my right within reach.
Alternative situations: I am sitting on a chair next to the trash can on my right talking on my cellphone to my boss. I am sitting on an office chair with my arms tired from working, while my feet are on top of the office chair that is on my 10 o'clock.
Question: Is the amount of trash cans at my right odd or even?
