MISS MANNERS by Judith Martin, Nicholas Ivor Martin and Jacobina MartinDEAR MISS MANNERS: I live in a rural area where cellphone reception and internet service can be spotty, which sometimes results in calls being dropped without warning. But more commonly, an awkward exchange ensues, where each person tries to call the other back simultaneously and can’t get through. This seems logical, and I find myself wishing it could become established phone etiquette. Someone more knowledgeable about the inner workings of telecommunications than Miss Manners will have to explain to her why its bugs appear to have longer lives than its products. Please send your questions to Miss Manners at her website, www.missmanners.com; to her email, gentlereader@missmanners.com; or through postal mail to Miss Manners, Andrews McMeel Syndication, 1130 Walnut St., Kansas City, MO 64106.
