Crows(1994)

A thin child of about 10, nicknamed "Crow" because she mimics the bird, has no friends and rejects a teacher's hug. At home, she is left on her own, her mom locks her out while entertaining a lover or is asleep. One morning, Crow sees a chubby, cherubic child hugged by both parents as the father leaves for work. When the toddler is left alone, Crow lifts her through the fence and kidnaps her.
