9. Because I Said So (2007)
When attempting to find your way into a womans life, you will find it best to have allies. Knowing her friends can result in obtaining crucial, secret information, such as favorite flavor of ice cream, or most traumatic life experience. Coworkers are great, too. If the people she interacts with every day root for you, that will indeed have a subconscious impact on your targets feelings. Without question, the greatest ally you can have is her mother. Diane Keaton and Mandy Moore demonstrate this in Because I Said So. No one else will have such an interest in your target, let alone the entitlement that enables her to meddle so thoroughly in her daughters life. Remember, though, that youre playing with emotional fire. Develop too strong of a relationship with Mom, and it will be harder to eventually kick that girl to the curb.
