Its official. My grandmother is going crazy. She claimed that I answered the phone when the nurse called to set up an appointment for today at 10am. She said I wrote the time on the calendar. Lol. What I remember is her answering the phone talking to a "nurse" but no recalling what the lady said when she got off the phone. Its a time over here.
