This is Barbara, she thinks she has a steady boyfriend, and she thinks he is cheating, she thinks revenge is in order.
Barbara wanted revenge for her boyfriend getting-it-on with other women. So, she says, quote, "I prayed about it and stuff" as she looked for guidance on what to do. Not sure who she was talking to but she then jumped on his Volvo. Watch her blast through the windshield, because that is normal. Who do you think she is on the phone with?
