We celebrate Halloween on the 31st of October. This festival is very popular in English speaking countries, such as the United Kingdom, the USA, Australia, etc. The most well-known symbol is the Pumpkin. At night people go out in fancy dresses like monsters, skeletons, witches, ghosts, vampires, etc and they play "Trick or Treat", and sing songs like the following one:
"Girls and boys go out to play,
the moon is bright on Halloween night,
take your candle, take your mask,
the moon is bright on Halloween night!!
Look for witches, look for ghosts,
the moon is bright on Halloween night,
Abracadabra, wizzy woo,
I want to play with you!!"
