Picture this: I’m visiting a friend whom I haven’t seen in years.

We’ve been able to stay in touch on the phone and by email. I’m traveling through her hometown and we meet for lunch. We hug, squeal, exchange “oh you look so good” comments, and then order our lunch. As we eat, we catch up on our kids and lives.

After the first frenzy of conversation, she’s less chatty. She doesn’t answer my questions very quickly. She seems so distracted. Our conversation loses its rhythm.

Then she says something about someone she’s following on Twitter, and I think, “Where in the world did that come from? I don’t even know who she’s talking about.”
