The supervisor doesn't like my grammar. Specifically, my misuse of commas.

That may actually be the first time in my life anyone other than my mother has seriously corrected some technical aspect of my writing. Shock, thy name is Dee.

However, he pretty much did like everything else. I almost flinched when he handed the first chapter draft back, and when he said: "It's good. Maybe just a paragraph on the end linking it into the whole?" I almost melted into a relief-tinged puddle of Dee.

But he has a really nice carpet, and I didn't want to mess it up.
