 Right. And so how many kids do you have? I have two kids, both in high school. And so have you done this with them? Have you told them, give me your cell phone? Well, they're in high school, so they passed the limit. Did you try to hold it back? We didn't because I didn't know back then. So we gave my son a cell phone when he started walking to school. So I learned early on from Lenore Skenazy, who's my partner in this. She wrote the book, Free Range Kids. I learned that we need to send our kids out. So I'd sent my kids out on errands. And when my son started walking to school in fourth grade, we gave him my old iPhone.
