"I have a hard time sometimes accepting that I'm an adult and that I can actually be an adult in situations like this," she explained in a Facebook video. "You feel like these kids are intimidating to you. I'm just not very confident sometimes in my adulthood. But I felt like something needed to be done about this. So I set my cart aside, and when the kids checked out, I walked out and said 'Excuse me. You need to stop.' My heart was racing because I'm very non-confrontational, but anyways, I said 'You are being very cruel to that man,' and the kids stopped and they were looking at me like 'we're in trouble.' And in that moment, I realized, yes, I'm an adult. This is OK. I can take control of the situation and teach these kids a lesson."
