As far as I’m concerned there’s no reason to focus on punctuation in your posts now that we know you are following an accepted style. However, it is important for the rest of us to understand these different styles, so we can offer better advice to every poster who posts work on this forum. Not everyone who posts here is American, and we should understand and respect their styles, I would think. Or in other words, it’s important we know the rules so we don’t try to correct something that isn’t technically a mistake. We won’t learn anything if we don’t discuss. Sorry it frustrates you.
I thought the dialog in this ‘baby shoes’ piece was pretty good. The only place I stumbled at all was when the mother spoke, because I thought it more likely that she’d mention the new baby BEFORE she asked if they were hungry and all that other stuff. *shrug* Just a thought.
The dialog in your other piece, the old men in the park, that was hilarious and worked well, in my opinion. Any other specific questions you want us to address? 😀
*I looked up the U.K. edition of one of my favorite books by an Australian author, and guess what? They used single quotation marks around dialog. My U.S. edition uses two.
