Texters getting on your last nerve? You’re in good company. The talented Janae at Claire & Me Designs created these elegant little cards for just such an occasion. Save yourself the trouble of shouting, throwing things, or punching the offending party square in the nose.

In countries where mobile phones have long been part of everyday life, there are certain unspoken social rules for using one’s phone in public. For instance, in Japan, people who talk on their phones while using public transportation (subway, bus, commuter train) get intense stares until they end the conversation. No one wants to overhear a stranger’s one-sided phone conversation.

But here in the States, we’re relatively new to cell phones. American society has yet to formulate basic cell phone etiquette. I think we’ll have plenty of social rules for cell phones in another five or ten years, though. Until then, we’ll have to work it out as best as we can with our fellow travelers, customers, friends, family, and students.

Most people—including my students—have a good sense of when to leave their phones on silent and in their pockets. Most realize on some level that texting during someone’s presentation (class, church service, concert, play, etc.) is downright rude. They know that it tells everyone else that the texter just doesn’t care. Thank goodness for these people.

The rest? They’ll learn—eventually.
