Quote from : Harry Potter and the Deathly Hallows: Part 1 Movie

Charity Burbage: [crying and pleading] Severus, please! We were friends...
Lord Voldemort: [Snape stares blankly at her. Voldemort raises his wand] Avada Kedavra!
Lord Voldemort: [Charity's body crashes onto the table. Voldemort caresses Nagini as she slithers across the table] Nagini... dinner.
