Re: Require explanation in past continuity
The vast majority of what I write is in a business setting. My overall goal is clarity. Sometimes I can have a bit more fun with my writing and get to play with the "voice" we use, but usually it's pretty straight-forward stuff. How your student loan works. What you can do to make your landfill closing more sustainable. The difference between short-term and long-term disabilty insurance. Case studies, brochures, presentations, articles, customer letters, employee communications, procedureal guides -- all things I've written.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
