Mason wanted to know whether strangers could find our house.

‘Not from that picture,’ I said, ‘but we need to be careful about what we share.

You can enjoy photographs without everyone having a right to see them.’

‘Can we still send Grandma Ruth pictures?’ Delilah asked.

‘Of course.

Sharing with people we trust is different from posting everything for strangers.’

Later that week I stood in my office, looking at the frame on the wall that held our family’s first professional photograph.

Four newborns, a very tired young mother, and an exhausted nurse who had agreed to help arrange them for the camera.
