I was teaching the use of commas yesterday and something came up that I've always been sketchy on. It's about using punctuation with quotations. Here is an example: "Take the dog for a walk." said dad to Jane. "Take the dog for a walk," said dad to Jane. Which one of the above would be correct. The quote is a full sentence, so I feel like I should end it with a period, yet that seems to leave the last part just hanging. In the second example, the comma keeps everything together, but I feel like the quote should have proper quotation for being a full sentence, not just a comma. Is this one of those things where both ways are commonly accepted? I know I can't use both the period and the comma, but I'm not sure which one is most appropriate. What do you think?
