"There are only two rules you must obey as a writer: You have to use words, and you have to be interesting. Everything else is wide open." Richard Bausch (Blatantly Thieved from Facebook.)
So, writing has rules. I've read several different books about these rules. Robert's Rules for Writing,101 unconventional lessons every writer needs to know, Eats,Shoots, and Leaves, The Bedford Handbook, just to name a few. I don't have much to add to all of the blah blah blah other than to say: Them rules is a good idear. All writerly types should foller 'em, and don't never use no double negativers. Ifn' you do, do it in triplication.
Also, YOUR, YOU'RE or THEY'RE and THEIR and THERE should always be replaced with the more eloquent: You-ins and y'all and thems.
Considering the origins of the English Language...The southern dialect is actually closer to Old English. If you are the cracker, be the cracker. Don't be a cracker trying to a cheese puff.
