Probably bad for your hearing too

For reference, the loudest sound ever on earth was 180dB https://wikipedia.org/wiki/1883_eruption_of_Krakatoa
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.
Fair enough. I had some pretty annoying kids in my classes but I never thought to rip them apart in front of everyone!
Your attitude is appreciated! That's the only time it ever happened to me, so either that lady was an outlier or I got better.
