I am teaching a class when one of my three students reminds me that this is our last day. One of the students mentions our boxes and we each go to retrieve a key to unlock our boxes. My key is at the bottom of a box that had some random things in it. I notice that there are actually two keys. We all go to a room where there are walls and walls of various safety deposit boxes. I begin scanning the rows for my box, looking first at the number on my key--152. That is when I notice I have two keys but I continue seeking the first box. The students have not only found their boxes but have already emptied their individual boxes. I continue looking and realize that there is a gap. A curator comes and asks to see my key. I show him the small ring with two keys on it and he says that because I have two keys my boxes are somewhere else and I need to follow him. The students come along with me, curious about what my box contains as am I because I had forgotten I even had a box let alone two.
