Correct the following paragraph for consistency in tense, person, number and tone: The issue of doing what is right can be a difficult one for a foreign student. Sometimes, the difference in how two cultures viewed things was extreme. It can even drive you nuts. I remember once my instructor asked to see me in her office later that afternoon. I agreed to see her at 3:00, but then my sister calls me on my cellphone. She said she has a flat tire and is waiting on the road. Of course, I went to help her. The next day, my teacher was very aggressive and asks me why I didn't see her yesterday.
