When I was in 7th grade, I had a lot of trouble in reading. My mother used to sit by my side, and explain each paragraph of each school reading assignment to me because I didn’t understand what I was reading. She would have to read each paragraph to me, and then after each paragraph, she told me the general meaning of what we just read.
In class, I tried to hide the fact that I couldn’t read. My teachers gave us the last 10 minutes of class to start our reading homework, and I would sit there for the last ten minutes of class staring at the page, pretending I was reading it. I remember a terrible feeling of not wanting to get into trouble for not being able to understand. I had to wait until I got home so my mother could explain it to me. How did I ever get into Cornell University
