Inspiring Others to Financial Responsibility
"quiet disappointment is far more effective as a response to someone who has let you down than a pile of rage ever will be. If someone lets you down, do everything you can to avoid exploding at them. Don’t let your emotions overwhelm the situation. Instead, calmly state that they did, in fact, let you down"
I think this is a good strategy for any situation. Too bad we see exactly the opposite most of the time.
