A childhood belief about classes

When I started elementary school, I was taken out of class by a woman who tested my math and reading skills. I never knew that I was being tested because I excelled in these subjects. When I realized that this woman was the special educator, I was dumbfounded. How could I have a mental, physical or emotional disorder without noticing. I concluded that I was mentally handicapped, which led to all of the individual testing, and my friends and family didn't want to hurt my feelings by telling me. It wasn't until a few years later, when I went up a grade for math classes, that I realized I was not mentally disabled.
