Many students in the US say that they've been bullied at school. Natalie Hampton is a high school student who was bullied a lot in middle school. She often had no one to sit with at lunch. So she created a phone app called "Sit With Us." This app lets students sign up and post when there are free seats at their lunch tables. These students have promised to be kind to those who come sit with them. Hampton hopes her app will help students find people to sit with without fear of being bullied.
