Because, at my age, it's good to have a refresher, and because there were several mistakes my editor found in my latest book Ian and Edward, I decided to read English Grammar for Dummies. There are so many things I'd forgotten about since my school days like:
1. Don't split your infinitives
2. It's all right not alright
and
3. Don't take PE after lunch
So, my advice for today is: refresh your knowledge base. It'll be good for you, and then you won't feel so much like a dummy.
Cheers!
