Many children dress up in fancy costumes and visit other homes in the neighborhood. At each house, they demand sweets, snacks or a small gift. If they do not get this, they threaten to do some harm to the inhabitants of the house. This is known as playing 'trick-or-treat' and is supposed to happen in a friendly spirit, with no nasty or mean tricks being carried out. However, if your children take part, it is important to accompany them and to check their 'treats' to make sure they are safe to eat or play with.
Some families carve lanterns with 'scary' faces out of pumpkins or other vegetables or decorate their homes and gardens in Halloween style. These were traditionally intended to ward off evil spirits. If you are at home on Halloween, it is a good idea to have a bowl of small presents or sweets to offer to anyone who knocks on your door. This will help you to please the little spirits in your neighborhood!
One cause that ties with Halloween is collecting donations for the United Nations International Children's Emergency Fund (UNICEF). As children trick-or-treat on Halloween night, some of them might carry small cardboard boxes with the UNICEF logo on them and collect coins instead of the usual candy. The money collected is then given to UNICEF and used to help needy children worldwide.
