It is used when the participants discuss a need for someone else rather than themselves. For instance, describing the need for firewood to keep the kids warm.

Utterance: 'ok, so to make sure we're on the same page. You get 2 food, 2 water and 1 firewood. I will take 1 food, 1 water, and 2 firewood?'
Output:
No
