Throughout the halls of the Leroy H. Smith School in Winterport, strategically placed mirrors show more than reflections to students as they walk past. Special messages are posted next to the mirrors that are intended to encourage and cheer the pre-kindergarten through fourth-grade students who attend the elementary school. Around the corner from a classroom, or across from the cafeteria, students can catch glimpses of themselves in mirrors with the frames spray-painted in eye-catching primary colors and then read words such as “I matter,” “I can make good choices,” “I make a difference” and “I am beautiful.” Dawn Moore, school principal, said a teacher had seen the idea of positive self-talk mirrors on Facebook and brought it to her attention.
