Although this resembles the older tradition of guising in Ireland and Scotland, ritual begging on Halloween does not appear in English-speaking America until the 20th century, and may have developed independently. The occupants of the house (who might themselves dress in a scary costume) will then hand out small candies, miniature chocolate bars, and sometimes even soda pop. Some American homes will use sound effects and fog machines to help set a spooky mood. Other house decoration themes (that are less scary) are used to entertain younger visitors. Children can often accumulate many treats on Halloween night, filling up entire pillow cases or shopping bags.
In Scotland, children or guisers are more likely to recite "The sky is blue, the grass is green, may we have our Halloween" instead of "trick or treat!". They visit neighbours in groups and must impress the members of the houses they visit with a song, poem, trick, joke or dance in order to earn their treats. Traditionally, nuts, oranges, apples and dried fruit were offered, though sometimes children would also earn a small amount of cash, usually a sixpence. Very small children often take part, for whom the experience of performing can be more terrifying than the ghosts outside.
Trick or treat, you're so neat.
Give me something good to eat.
Nuts and candy, fruit and gum.
I'll go away if you give me some.
Trick or treat, smell my feet.
I know you'll give us lots of treats.
Not to big, not to small,
Maybe the size of Montreal.
Trick or Treat, Trick or Treat,
Give me something nice to eat,
If you don't we don't care,
We'll put money in your underwear
A child usually "grows out of" trick-or-treating by his or her teenage years. Trick-or-treating by teenagers is accepted, but generally discouraged with genial ribbing by those handing out candy. Teenagers and adults instead often celebrate Halloween with costume parties, staying home to give out candy, listening to Halloween music, watching horror movies or scaring people.
