Hi, happy Halloween! I'm Veronica, I live in United Kingdom and we do celebrate Halloween. What we do is at the evening we go trick or treating, trick or treating means to knock at houses' doors and say "TRICK OR TREAT!" and then the person that opened the door is supposed to give you candy.
SAFETY NOTE:

• Do NOT come go inside houses because someone might kidnap you!
• If a person doesn't give you candy, DON'T throw eggs at that house or be rude!
• You should walk with your parents at Halloween because it's really dark!

 
I really like Halloween.This year I'm dressing up as Dead Little Red Riding Hood.
