"I think promising goes back to the unstated contract between a mother and child. It's no use her telling a child, 'You must not go near the edge of the cliff, or touch fire, or wander off,' unless the child agrees that it won't. If the child doesn't agree, then the mother must be more vigilant than is practical. What the child promises is to try to stay alive. What the mother promises, in return, is to love the child and try to keep it alive. That is the earliest contract humans make, or have ever made. So, when we ask a [crisis line] caller to promise, we are touching an ancient nerve. The equation written in our cells, in our bones, is that keeping yourself safe will lead to love. It is the oldest and simplest promise."
