This means that, for example if a group or two people are having an argument it’s best that it doesn’t in with one side of the argument winning, or feeling as if they’re more correct than the others. It’s best that both people or peoples feel like they’ve won in the argument, this way it wouldn’t involve any long term conflict.. which could lead to something very unnecessary or sometimes even harmful to both people.
Crying is the conditioned response because he now cries when she gets her keys from the hook because he's been conditioned to know that she's leaving when she does that.
Best of luck!
