Halloween is a celebration on the night of October 31. Children wear costumes and go to people's homes saying "Trick or treat!" to ask for candy (sweets in the UK) and people give it to them. The suggestion is: "Give me a treat or I will play a trick on you." People mainly dress up as ghosts, witches, or other scary things for Halloween. Halloween is a day that is not yet celebrated much in the Netherlands. It is often compared to our "Sint Maarten" because then children come knocking on the door for a treat. In many other countries, Halloween is celebrated on a grand scale. Surprise those recipients with these cool Halloween cards!
