You are in a office room facing towards the wall. Now walk straightly and exit the room and keep on moving straight till you reach the grey wall with some painting. Take a left turn, now you are near a white shelf with two blue glasses in one of the shelf. Walk across that shelf. Now there are four chairs with a glass round table. Pass through them. So there is a narrow walk way in front of you. So the point which is in between the yellow chair and the glass door will be the final point.
