A well-known British author Alan Sillitoe has always tested the quality of his writing by seeing how it sounds when he reads it aloud.

I've always done that with my writing, too. It makes a big difference sometimes.

I am going to send a link for this thread to the senior editor to whom I sent my editing test. I am sure it will get a chuckle and then, he'll probably want to hire the lot of you! Oops, maybe I'd better not until I know I have the job!**bg**

I agree with Janie and Uncle DaveO,though, a creative writer will use various voices depending on their characters and thus "correct" grammar will vary also.
