"Deliciously hilarious. If you care about people and enjoy a good laugh, I politely encourage you to read this book. Immediately." -- Adam Grant, bestselling author of  Originals From the brilliant comedic mind behind the hit movie  Yes Man , a hilarious and pitch-perfect look at the rudeness that's all around us -- where it comes from, how it affects us, and what we can do about it You're not just imagining it: People are getting more and more rude - from cutting in line, gabbing on their phones and clipping their nails on public transportation, to hurling epithets on Twitter and in real life (including a certain President who does both). And the worst part is that it's contagious, leading reasonably courteous people to stoop to new lows in order to respond to the ever-coarsening encounters we face every day. In this engaging and illuminating new book, bestselling author and all-around curious guy Danny Wallace looks at the reasons behind the rudeness, and what we can do to stop it. His quest to stop the madness includes interviews with neuroscientists, psychologists, NASA scientists, politicians, and other experts. He joins a Radical Honesty group, talks to LA drivers about road rage, and confronts his own online troll in a pub--all to better understand the scourge that's turning normal people into bullies, tantruming toddlers, trolls, and other types of everyday monsters. Want to be part of the solution? Let Danny Wallace be your smart and funny guide. "A meaty cry for human decency, wrapped in a deliciously hilarious hot dog bun. I plan to read it again and then force-feed it to my neighbor, my mother, and my college roommate. If you care about people and enjoy a good laugh, I politely encourage you to read this book.

I therefore refused to give anyone food until every single one of them was sitting down in their seats. Unfortunately, I had to treat them like primary school students.”   Poor Omar just hadn’t known what he was letting himself in for. In subsequent blogs and tweets, you can tell he was becoming with­drawn. He talks of loneliness; he has trouble peeling potatoes; he spends his free time trying to find chocolates or feeding a local cat called Lucy.   What Omar perceived as the rudeness of others really affected him: this kind of behavior was not what he signed up to ISIS for, and it was wearing him down.   It only got worse.   “In the West, it is common knowledge to walk out of a room wearing the same pair of shoes that you wore while entering the room. Nay, it is common sense!” he wrote at one point, and you know some­one’s annoyed when they use words like nay. “However, here in Sham, our Syrian brothers [. . .] believe that everyone can wear each other’s footwear. Sometimes you would enter a building and when leaving, you would see the person with your shoes walking 100 yards ahead of you and it can be quite irritating.”
