Situation: I am sitting on an office chair with the table on my left, a keyboard in my eleven o'clock direction and nothing in front of me.
Alternative situations: I got a phone call and sat on another office chair, I just moved from the office chair on my left because I do random things when talking on the phone. I relaxed in the office chair and ate my lunch at the table to my left.
Question: What do I need to do to turn on the lamp if it gets too dark?
