How often do you use the phrase "good morning"? And how often do you use the phrases "good afternoon" or "good evening?" I say good morning or, alternatively, mornin' quite often. But good afternoon makes me feel like some old timey gentleman who's taking off his top hat and inviting you to tea and good evening makes me feel like that or like a Bond villain. Sure you might say these things on the phone occasionally, but how often do you say them in person? Discuss.
