At almost every social gathering with non-math teachers I attend, I hear some version of: “Oh proofs, I hated that when I was in high school” when I share that I teach high school geometry.

However, even in our formal geometry and honors geometry classes, we still tend to largely ignore the "two-column" proof. By the time I'd left the 9th grade, I could do 2-column proofs in my sleep.
