Omg me too!! I was in 5th grade. I might have been 10, though. I remember when it happened, too. Since my birthday is later in the school year, I was probably 10. It was right after lunch one after noon, and I sat down in class and tried answering a question on the board as usual. I don't remember if I raised my hand or not, but anyways when I gave the answer to the question, I noticed I stuttered! I was like to myself, oh, I just stuttered? Oh well, I guess I'm a stutterer now? I didn't really think much of it, honestly. Little did I know what was ahead of me :(
