Ernest Hemingway said this quote

When you have two people who love each other, are happy and gay and really good work is being done by one or both of them, people are drawn to them as surely as migrating birds are drawn at night to a powerful beacon. If the two people were as solidly constructed as the beacon there would be little damage except to the birds. Those who attract people by their happiness and their performance are usually inexperienced. They do not know how not to be overrun and how to go away. They do not always learn about the good, the attractive, the charming, the soon-beloved, the generous, the understanding rich who have no bad qualities and who give each day the quality of a festival and who, when they have passed and taken the nourishment they needed, leave everything deader than the roots of any grass Attila's horses' hooves have ever scoured.
