I don't know the title but the song went "this little light of mine I'm gonna let it shine....and the song goes on," a post from a woman named Myra Hilliard said. "Anyway. Don't allow someone else's action to blow out your light. You are at Wegmans for a purpose. You are the light that brings joy to people. Keep the light within you shining and share it with all.
