Halloween is a widely celebrated holiday with origins in ancient Celtic traditions. It has evolved over time and is now characterized by dressing up in costumes, carving pumpkins, and going trick-or-treating. The phrase “trick-or-treat” originated as a playful threat, with children promising to play tricks on homeowners if they didn’t receive treats. It has since become a lighthearted way to merge the traditions of dressing up and receiving treats, while also promoting community interaction.
