Halloween is a special time when children get to wear a costume and go trick-or-treating. Children love to figure out what costume they will wear. And there are so many options! Maybe a scary vampire or a beautiful princess or a brave knight in armor. Maybe a mermaid or a robot or a goblin. How will they ever decide? It's easy! They pick their favorite, the one they like the best. And then they'll be ready to answer the question that everyone keeps asking.
