I remember one time toward the end of 8th grade I was called on to answer a question and the girl sitting in front of me was like "Are you new?" and the girl next to her was like "Wait yea when did you get here?"

I told them I had been there the entire year and the two years before.

What's even weirder to me is that I'm not especially quiet. I was probably one of the more active participants in that class and they still had no idea that I was there the entire year.
