I don’t use Facebook for much more than keeping up with family members, but recently noticed I had a message from a summer camp friend from when I was 13 (I’m almost 30). We were close as kids, and became Facebook friends at some point, but haven’t communicated since. He and I now live in the same city, and he wants to meet up. I bear no animus toward this person—how could I?—but I have no desire to rekindle a friendship I’ve let lay fallow for nearly two decades. I know he’s seen that I’ve read the message: Do I need to reply?
