Do I Look Like Betty?

I walked into a room to answer a call light. The patient gasped, grabbed my hand and started to tear up. She began saying, "You're here. I can't believe you're here." I just smiled while wondering why she was so glad to see me. The call light hadn't been on that long. Then she asked, "What are you doing here?" I said that I was answering the call light. Suddenly, her face dropped and she said, "You're not Betty?" The confusion was cleared up, but I sure hope that Betty comes to visit. It would make her so happy and I would like to see what she thinks I look like.
