when more than one car approaches an intersection at the same time. All the cars stop and wait, each insisting that the other goes first.

In the third Minnesota Standoff of the evening, the last piece of pumpkin pie sat alone in the center of the table, the whole family eyeing it in uncomfortable silence.
