I guess I'm on a punctuation march. Last week it was the eclectic ellipsis. This time it's the exclamation mark. Of course, we all know that it's used to denote an exciting sentence. In children's literature some of us get carried away, however, with placing it at the end of every sentence in dialogue. We can't help ourselves.
"Hi, Mary! School was fun!"
"It sure was, Billy! I can wait to go back tomorrow!"
"I don't think so! Tomorrow's Saturday!"
None of those sentences actually require an exclamation mark, except Billy's last one. Maybe. One might well wonder whether one even needs such a badly written conversation -- ever -- in their manuscripts. But I digress. What about exclamation marks? Tell us your secret uses for it.
