In terms of how to be a good human, the invisible script society handed me as a girl told me I was to be selfless, humble, nice, compassionate and forgiving. In relationships, when problems creep up, the first tool to reach for is always kindness and understanding. The most important rule is to never be selfish. If things get tough, try being more accommodating, more easy-going. Let things go. Don’t be a nag. Keep the peace.
