Punctuation might change the meaning.

Grammar Rules Project
I think it is interesting that punctuation can change the meaning of a sentence.  Some writers don't think about this.
For example, "Keep drinking Haymitch."  A comma is needed after "drinking" or the name of the drink is "Haymitch."   This was a sentence from an advertisement about the movie "The Hunger Games."

 I found two more examples  in the book Eats, Shoots & Leaves written by Lynne Truss.
 Page nine includes the following sentences:

"A woman, without her man, is nothing."
"A woman: without her, man is nothing."
