Situation: I am sitting in the armchair facing the table, while there is one more armchair on my left. A board is standing on my immediate right.
Alternative situations: I am sitting in a chair talking with my brother on the couch to my 2 o'clock. I am filling out a form on the table, there are two armchairs behind and on the front-left side of the couch.
Question: Is light coming in from my left?
