Kyllene is a ladybug while Darrielle is a fairy.
Why are they wearing these costumes? For their trick or treat. And I do hope they had a lot of fun.
What is trick or treat? Read here...
Trick or treat, Smell my feet Give me something good to eat !!!
The history of "Trick'O'Treating" can be traced back to the early celebrations of All Soul's Day in Britain. The poor would go begging and the housewives would give them special treats called "soulcakes". This was called "going a-souling", and the "soulers" would promise to say a prayer for the dead.
Over time the custom changed and the town's children became the beggars. As they went from house to house they would be given apples, buns, and money.
During the Pioneer days of the American West, the housewives would give the children candy to keep from being tricked. The children would shout "Trick or Treat!".
