One of the times any person has been unfair to me was with project I did in 8 grade. This was a simple project where we were going to read a book with the little kids. When we arrived at the classroom, there weren't enough kids for each group of students. Some people, including me, weren't able to do their project, and it was, somehow, "our fault". Our grade was going to be 1, this being unfair since it was not our fault.
