I employ this techinque daily. I always respond to questions and try to keep in touch with people to show them that they are important to me. Even if a person is mad at me or we are having a bump on the road, I still treat them like a friend because that is larger than my slighted feelings for a moment in time.
We tend to lose focus on whats truly important in life....all we got is each other. Theres nothing more or less. Simple as that.
