When I was in high school my English class had to read The House On Mango Street, which at the time I believed was the worst book I had ever read. We had to write a paper on the book, talked about it for days, etc. I decided I'd write a scathing analysis of the novel, not just criticizing its feminist preachy bullshit but also complaining about the female main protatonist, who I felt was a dumbass. There's a part where she wears a red dress somewhere and gets raped...and I wrote that her attire played a role in the attack.
One of the girls in the class asked to read my thesis one day, and so I handed her my paper. She read it, looked at me, handed the paper back, and walked away. Needless to say I got a bad grade - a C, which in hindsight was extremely generous; later my teacher (who was also my counselor) calmly explained to me how ignorant my argument was. Later I found out the girl who read my thesis was a rape victim. We graduated together, and I apologized to her for what I had written, and explained that I no longer thought like that. She accepted my apology and said that multiple guys in the class had come to similar conclusions at the time, and she was glad that I realized I fucked up.
Definitely the most embarrassing thing I ever did in school, in hindsight. I'm glad I was able to make up for it though.
