Expat,
You have two choices:
1. Buy lots of candy, stay home and pass the candy to the array of monsters who come to the door.
2. Buy costume, knock on other people's doors and say "trick or treat" then collect candy.
Halloween is great fun. The first year in my house I bought a load of Candy. My son went out trick or treating and came back with a load of candy. About six kids turned up at our house that was all. I think it was Easter before the two of us had finished eating the candy.
We live at the end of a cul-de-sac with about 10 houses in the road. There are no sidewalks and no street lights and I think the kids avoid the road because of the slim pickings. Last year I wore my sons mask from the previous year. I embarrassed my wife by hobbling along behind her shouting "I vant to see der chilldren, I vant to see der chilllldren"....She doesn't quite get into the spirit of it.
