Can I confess something to you? There’s one thing Aileen does that really bugs me. We will be talking together and enjoying one another’s company. But then, as we chat, I’ll hear the telltale buzz of her phone. And I can tell that I’ve lost her. I can see it in the look on her face, I can hear it in the tone of her voice. She goes from making eye contact to breaking it, from engaged to distracted, from involved in conversation to muttering toneless “uh huhs.”
