Friendship is one of the greatest pleasures that people can enjoy. A true friend does indeed share joys and sorrows with us. In time of trial, he or she is always at our side to 
give us his or her help and comfort. A true friend can always be trusted, loved and respected. They help each other when they are in trouble, and cheer each other when they are upset. The most important thing is that a friend always understands you.
