DW loves halloween. She makes me help her decorate the house with strings of halloween lights and various goblins in the trees. The front yard gets filled with lighted gargoyles. Then when the kids ring the doorbell we answer wearing masks and offering plastic bats, vampire heads, spider rings, etc. We quit handing out candy a couple of years ago. I was skeptical that the plastic haloween figures would be accepted, but in a neighborhood of dozens of homes offering candy, the little toys are a big hit.
It's interesting that our two cats normally spend a lot of time sitting in the front window watching activities in our cul de sac. But during trick-or-treat time, when their presence would add to the halloween ambiance, they hide in the back room.
