In 1979's Love on the Telephone, Foreigner sang about the perils of long-distance relationships (which in those pre-Skype days depended on how good the participants were at romantic chat). In 1984, Stevie Wonder Just Called to Say I Love You (probably interrupting whatever "you" were up to). Cellphones made calls more intimate – at last, you didn't have to conduct your affair tethered to a wire in the middle of the living room. And unlike texts, which can be screen-capped, read aloud and sent to everyone, a phone call stays in the moment. (Unless, of course, you're recording your calls. And if that's the case, what is wrong with you?)
