I think that pesky little Elf is back! I came home from dropping my son off at school and thought I would change my blocks that said Happy Birthday to happy Halloween. This is what I found. After texting two of my daughters I still didn't have an answer who did it. Mystery was solved when my third daughter came home from school. She was trying to change the letters to say poop on a stick but didn't have enough letters. Only in my house! Haha!
