Why would they come to wg to critique their friend? They came here to remark frankly on them. If they got too specific with language 1. It'd make it obvious to their friend that it was them when the same critiques appear in their inbox as appeared here and 2. They'd potentially out them by describing their writing quirks and failings.

This is a remark on how they struggle to critique them, not an actual sample of their critiquing method.
