Although some of Perry's lyrics are questionable -- like the behavior referenced in "Last Friday Night" -- others have inspirational, empowering messages, like "Firework." Perry's many young fans tell the audience in recorded messages how much her music has meant to them or helped them overcome a sadness or difficulty. Perry has a loving, supportive family -- from her sister Angela to her very religious parents, who accept Perry despite the secular nature of her lyrics -- and a group of close, loyal assistants and support staff.
