Every Sunday evening in parking lots across our country a ritual unfolds.
A car drives in and parks next to another. A man climbs out of his car and opens the passenger door. Children climb out.
Hugs are exchanged.
A woman climbs out of the other car and opens her passenger doors. The children take a one last look at their dad and climb into mom's car.
In the best cases a few pleasantries are exchanged. Sometimes the parents can't manage even that.
They drive away only to repeat the ritual in two weeks.
