The person who always takes the family photo is never in it. Grab the phone and get them in the picture.

Somebody always ends up behind the camera, and across years that absence turns into a strange gap in the record. The person who did most of the work of the holiday is missing from every picture of it. They rarely ask to be included, partly because taking the photo is their way of looking after everyone.

At the next gathering, take the phone out of their hands and send them to stand with the others. Then take a second one that is actually good. It costs a minute and it fixes something that would otherwise be permanent.
