You’re not imagining it. People are getting more and more rude.

They yak on their phones. They cut you off in traffic. They clip their nails on public transportation. 

Author Danny Wallace says that rudeness is like a virus — once you’re exposed, you’re more likely to pass it on. In his new book, F You Very Much: Understanding the Culture of Rudeness — and What We Can Do About It, Wallace identifies the virus, brings it into the sunlight, then helps us seek solutions to curb the surrounding rudeness.
