On Feb. 28 at 2:30 p.m., the students and staff of P.S. 155 will hold a brief remembrance in honor of 6-year-old Amar Diarrassouba at the intersection of East 117th Street and First Avenue in Harlem. Amar was killed there one year ago by a tractor-trailer truck. All are invited to attend as balloons will be released in loving memory of him. His parents, Sidiki and Meichata Diarrassouba, are hoping that legislation introduced last year in the New York State Senate requiring guards on truck wheels will be approved. For more information, contact Christopher Lynn at 917-385-0368.
