There is a difference between being nice and kind.

Every attack is a call for His patience, since His patience can translate attack into blessing. Those who attack do not know they are blessed. They attack because they believe they are deprived. Give, therefore, of your abundance, and teach your brothers theirs. Do not share their illusions of scarcity, or you will perceive yourself as lacking.T-7.VII.7: 4-8

A Course In Miracles teaches that an attack is a cry for help. The appropriate response to those who need help is a blessing albeit with setting appropriate limits and attempting to prevent further harm.

In Unitarian Universalism some of us join together to affirm and promote justice, equity, and compassion in our human relations. Tough love along with kindness is sometimes appropriate. There is a difference between being “nice” and being “kind.” Sometimes it is not kind to be nice especially when limits and structure are necessary to contain harmful behavior.

Today it is suggested that we consider the difference between being nice and kind. It is always appropriate to be kind but sometimes not appropriate to be nice. It takes self awareness and self mastery to be the bigger person.
