A 10-year-old Cambridge boy, who received national recognition following a Cambridge Chronicle story about his organization Liam’s Lunches of Love, was recently honored by the Boston Celtics for his work with those in need. Liam Hannon, a fifth-grader at the Morse School, was honored as a “Hero Among Us” during the Boston Celtics game against the Phoenix Suns on Dec. 3. Liam, with the help of his family, makes homemade lunches and passes them out to the homeless near his Central Square home. Along with the lunches --which can be any variation of peanut butter and jelly, ham and cheese, apples, oranges and potato chips -- Liam often includes little notes of encouragement: “Have a nice day” or “Try to smile.” “They just need a little kindness in their life,” Liam told the Chronicle in August. “Usually when we first come see them, they look really sad. But when we go over and talk to them, they light up.” The Celtics’ Heroes Among Us program, established in 1997, has recognized outstanding individuals who have made exceptional and lasting contributions to their communities.
