New York, Nov. 9 (Reuters): When it comes to bad manners, today’s society is pretty much a hopeless case, author Lynn Truss says.

That didn’t stop her front ranting about it in her latest book, Talk to the Hand, a self-described “moral homily” that attacks rudeness the same way she critiqued bad punctuation in her 2003 best-seller Eats, Shoots & Leaves.

“Please” and “thank you” are endangered in the public discourse, she writes in her new work, increasingly drowned out by inane mobile phone chatter, dismal customer service and the vulgar epithet she writes as“Eff Off.”

“I say in the book that I have a flame of hope (that manners will improve) but it’s very, very, very small,” she told Reuters in an interview on Wednesday, the day after her book came out.

The New York Times called it “a thin and crabby diatribe” in a book review, adding,“The author may have been good for only one book-length conniption.”

Truss said writing her 206-page rant was therapeutic.

“It really, really made me feel better,” she said.“I don’t know whether I’ve just dumped it all onto my readers. I may have made everybody else feel bad in the process”.
