Yup. Revisions knocked me down Several pegs... all the way from "I think I'm competent" to "how did I even get accepted into the program if this is what they think of my work?"

Or when you ask for feedback on the structure and what to include before you polish a bunch of stuff that would be cut or rewritten, only to be returned a half-finished low-effort style ("grammar") nit-pick of a draft with increasingly angry comments about repeated "errors", culminating with swearing at you, how dare you waste his time, how dare you not read his Grammar_Lesson.docx (God help you, you did) and submit a draft that doesn't follow its rules (it was largely compliant), you're a native English speaker anyhow and should know better, and what the fuck is compound 12a, you didn't define it anywhere but keep referring to it (it was defined in-text in the previous paragraph and in the figure above it), fix it all and the rest of the doc before you bother him again.
