We ask 18-year-old Chana Wiliford and her father in Texas if they'd be willing to have a conversation on tape in which each of them gets to ask the other the questions they've never asked before. In the conversation, Chana is half his child, half his peer.

Margy's a reporter. When she told her dad that she wanted to write a story about him, he said sure.

We think of our phone calls and phone messages as so transient. We have another example of phones recording personal history: this story from Barrett Golding in Bozeman, Montana, comprised of telephone messages about his father.
