Today we have a special guest – Katherine's cousin Andrei! Andrei is a sophomore in high school and we were hanging out the other night and I told him – I'm really worried about when my daughter grows up and is a teenager. I don't think I understand what I should be worried about with teens anymore. I'm totally out of touch. And we had this great conversation about vaping and social media and bullying and I felt a lot better about teens after talking with him. And after our conversation, Andrei said he'd be happy to come on the show. Andrei is here to tell us about vaping and cyberbullying!
