People have no excuse to write using incorrect grammar-especially if their writing will be seen by the public. A little proofreading goes a long way. For Carolyn Stevenson Silicato, a retired elementary school teacher, this carelessness has always been a pet peeve. In fact, it became part of a tradition in the district where she taught: anyone spotting a misspelling in a public place would be sure to tell her about it. Those collected missteps form the genesis for "More than 100 Signs That Prove Nobody's Purrfect ." She began taking pictures of misspellings that she saw along the roadways. After she retired from teaching, she carried her camera with her all of time and quickly gathered over one hundred pictures of highway misspellings. She divides them into the types of grammatical mistakes that people frequently make, from "Which Vowel Was That?" to "Wrong Words"-thus inviting readers and students to detect the errors in each of the one hundred signs.
