Normal Adolescent Behavior is a 2007 drama film written and directed by Beth Schacter. The film was an official selection of the 2007 Tribeca Film Festival. The film is the story of a group of best friends, all of whom are in a six-way polyfidelitous relationship. They feel that being with this group—and only this group—is more fulfilling and overall better than conventional teenage dating. However, Wendy (Amber Tamblyn) begins to question the arrangement after meeting the boy next door.
