I find it far more satisfying to forgive others than to punish them, even if they are unkind. We are all wrong at times, and hurt at times, and able to be less than thoughtful. We are impatient, bitter, cruel, and manipulative in varying degrees, and none of us perfectly pure.
So let's not be unforgiving. Let's give others a break even if they do not give us one. Let's be the bigger person. As many times as it takes, let's learn to let it go.
I refrain from punishing others. I am allowing and forgiving.
