What we can do is to live out our lives as best we can with purpose, and love, and joy. We can use each day to show those who are closest to us how much we care about them, and treat others with the kindness and respect that we wish for ourselves. We can learn from our mistakes and grow from our failures. And we can strive at all costs to make a better world.
You think that your silence on certain topics, perhaps in the face of injustice, or unkindness, or mean-spiritedness, causes others to reserve judgement of you. Far otherwise; your silence utters very loud: you have no oracle to speak, no wisdom to offer, and your fellow men have learned that you cannot help them. Doth not wisdom cry, and understanding put forth her voice? We would be well to do likewise.
It is the history of our kindnesses that alone make this world tolerable. If it were not for that, for the effect of kind words, kind looks, kind letters . . . I should be inclined to think our life a practical jest in the worst possible spirit.
