The Irish playwright George Bernard Shaw once said: “The worst sin toward our fellow creatures is not to hate them, but to be indifferent to them: that's the essence of inhumanity.” Abraham Lincoln said: “To sin by silence when they should protest, makes cowards of men.” Mark Twain said: “We are all like the moon. We all have a dark side we want no one else to see.” Pope Francis said, “It is a mortal sin to discard the elderly.” He also said, “We are all sinners, but God heals us with an abundance of grace, mercy , and tenderness.”
