We don't do anthing. I have better things to be spending my money on. Last night was the fist time we have ever had kids come and knock, it was the worst time possible. Plus I don't keep any sort of lollies in the house so I had nothing to give them, not even a pack of chips as we had been away and only got pack today and my pantry is empty.
DD1 actually got a little scared too by the costumes. For her, getting dressed up is fairies and princesses and Glinda the good witch.

DH is in America at the moment and he said it is pretty amazing over there though, I think it would be nice to see it where everyone gets involved and goes all out.
