Looking for a book?

I read this book a number of years back as a required reading in 6th grade. I can't remember the name or too much about it. It's either a children's book or YA. I don't really remember the plot, but throughout the entire book, you never know the protagonist's name or gender. It's all written in the first person and everyone who talks to the protagonist just speaks without using any names or anything. I remember going in depth about this aspect of the book in our in class discussions. If anyone knows what book this is or any books that has this aspect, it would be very helpful. Thanks!
