Situation: I am standing in front of a single trash can and facing it with a picture on the floor to its left.
Alternative situations: I threw my lunch away in the trash can and to my left was a picture I noticed. Finished the work at the table in my 8 o'clock direction and throwing jammed paper into a trash can in front of me now, spotting a picture in my 10 o'clock direction.
Question: Is the amount of pictures I am facing odd or even?
