How many times have you wanted to smack the cell phone out of your texting teen or twenty-something’s hand while you are talking to them? Or while they are eating dinner with you?

Do you have to accept the Facebook friend request from your co-worker? The answer to these, and more – oh so many more – pressing digital manners questions are in a new book – just in time for the holidays – from New York Times Social Q’s columnist Philip Galanes – Social Q’s: How to Survive the Quirks, Quandaries and Quagmires of Today.
