He asked us where we were from. We told him and asked in return. “I live in a tree in Africa.” We chuckled. Not that funny, but I’ve heard worse. We assumed he was joking, so we asked him to tell us about his tree. He did. Without cracking a smile. We asked what he was doing here, if he lived in a tree in Africa. He said it wasn’t difficult to get to. And we realized that we needed to try to find a way to end this conversation as quickly as possible.
