When to give in?

There are times to give in - when you're persuaded the other person is right; when the other person cares a lot about the outcome and you care little; when any solution is better than no solution and you need an answer immediately. But as a long-term strategy for dealing with difficult behavior, it's not going to help. Giving in rewards bad behavior, and what gets rewarded gets repeated.
