I think it was an overreaction in terms of its delivery, but I was homeschooled and started college early. I was the stereotypical socially inept homeschooler. The class was introduction to college algebra, which doesn't usually cover logarithms AFAIK; I brought them up unprompted during a quiet moment when the teacher was cleaning the whiteboard. I was curious about them because I had been reading my older brother's textbooks and found them interesting.

The other student's complaint about me was that I monopolized the teacher's attention by sitting front and center and raising my hand for every question. Additionally she felt that I was trying to show off. At that point I was also very visibly younger than everyone else, which did occasionally annoy people. (This became less of an issue when I hit puberty and started growing a beard.)

But I was oblivious to those kinds of things at the time and didn't realize I was having any kind of impact on anyone else in the class until the other student chastised me. Perhaps it was an overreaction, but the message was one I needed to hear, I think.

Also, to their credit, that student did apologize to me, more calmly expressing the nature of their grievances; I apologized in turn and said that I would try to be less disruptive.
