Bardot's childhood was prosperous; she lived in her family's seven-bedroom apartment in the luxurious 16th arrondissement. However, she recalled feeling resentful in her early years. Her father demanded she follow strict behavioural standards, including good table manners, and that she wear appropriate clothes. Her mother was extremely selective in choosing companions for her, and as a result Bardot had very few childhood friends. Bardot cited a personal traumatic incident when she and her sister broke her parents' favourite vase while they were playing in the house; her father whipped the sisters 20 times and henceforth treated them like "strangers", demanding them to address their parents by the pronoun "vous", which is used to address unfamiliar or respectable persons in the French language. The incident decisively led to Bardot resenting her parents, and to her future rebellious lifestyle.
