Romantic comedies are harmful to your marriage, at least according to an Australian survey.  The poll, released by Warner Home Video to mark the release of the film "Valentine's Day" on DVD, states that almost half the people who took the survey said that the happy endings in romantic comedies have ruined their view of an ideal relationship.  One in four people said they are now expected to know what their partner is thinking.  One in five said these movies made their partners expect gifts and flowers "just because".  An Australian relationship counsellorcommented that real relationships, unlike those in romantic comedies, take work and true love requires more than fireworks,  People, she added, are becoming "happy-ever-after addicts" who are losing touch with the real world.
