>kind (especially when others around us are unreasonable just because they can)
Think about why you want to be kind to such people. It is one thing if you expect your kindness to disarm them and be reciprocated and another if you don't. If you don't, you would only be rewarding and reinforcing bad behavior. Surrendering to avoid conflict is not a viable long-term strategy in any career but that of a monk. It is far better to learn to stand up to those who mistreat you without undue kindness.
