@Cel: Do you guys celebrate 'St. Maarten' over there? I know they do where I live, but I know that it isn't celebrated everywhere in the Netherlands.
For those who don't know: St. Maarten is to a certain extent our version of Halloween. We celebrate the day of St. Maarten (AKA Martinus of Tours) Kids go around town, but instead of saying trick or treat, they sing a song to get candy, and they carry their bags and a beautifully crafted lantern around, instead of a costume. It's pretty cute to see a 3-year-old at your doorstep and they do their best to sing 'Sintermèrte's vögelke' (one of those songs, in our local dialect)
After the whole going from door to door, we all gather at a central point, where St. Maarten does his speech (a guy dressed like St. Maarten) and we get a waffle and some hot chocolate. Then St. Maarten lights a bonfire.
In short, near me, we don't do Halloween, but we have St. Maarten instead.
