" Beware of getting involved with people who seem to be able to feel good but have no close friends. They may be witty and fun to be around, but their humor is all put-downs and hostility. If you marry such a person, you will soon be the recipient of that hostile humor and may regret it for the rest of your marriage. Look for someone who has good friends whom he or she treats well and whom you enjoy being with, too. Someone who does not have good friends does not know how to love. "
