This "trick or treat" thing is an American tradition, but I bet over there they don't tolerate kids vandalising property or otherwise intimidating people. I believe the tradition over there is much more family orientated, with whole families going round their neighbourhood together, beautifully costumed.
I for one dislike "trick or treating", however I keep a few sweeties to hand if I get a knock on my door, as I really don't want to be clearing eggs, flour off my car, or worse.
Does anyone do the same as me and take the coward's way out, or do you stick to your guns? What did they do to you?
