Laura Talmus felt helpless when her then-11-year-old daughter Lili kept calling her from school in tears. After her daughter passed away from medical complications in her sleep at age 15 in 2009, Talmus put together a video celebrating her life. When she showed the video, Lili's classmates were shocked to realize how isolated Lili had felt. The next year, Talmus ... and her husband channeled their grief into forming Beyond Differences, a nonprofit that focuses on raising awareness about social isolation in youth and providing solutions. Talmus believes the social isolation her daughter experienced is affecting students all over the country and contributing to serious health issues, mental health problems, suicide and school violence. Beyond Differences ... has now grown to reach over one million students in all 50 states. On February 16, 2,500 schools [participated] in No One Eats Alone Day, a day of action ... that encourages fifth through eighth graders to mingle, make new friends and become more aware and proactive about social isolation, especially at lunch. "No One Eats Alone is completely rooted in the experience Lili had," Talmus explains. "For many children, the lunch break or recess are the worst parts, so we started with that." Beyond Differences sends backpacks or "Belonging Boxes" with a lesson plan, games, toys, art projects, stickers and conversation starters to participating educators, at no cost to the schools.
