Punctuation is important.
I have to start taking the camera with me when I drive to town. I want to get a photograph of this one truck I see sometimes. On the side it says, "Ham Produce & Seafood Inc." It makes me wonder what the heck ham produce is. Or seafood inc, for that matter.
My daughter came up with another example of punctuation power earlier today. She was so proud of herself that she ran downstairs with a whiteboard and marker to show us:
No more than that.
No, more than that.
One little comma. A world of difference.
