We don't even do halloween in the NL...
We've got our own version called "Saint Maarten", where kids hand-craft some lanterns and go house to house to sing songs for candies.
And, I guess I can consider myself lucky that I don't work in a sector where I have to deal with harmfull chemicals.
I will, however, be working on a day to day basis with a completely undetectable force that can kill, burn, or even evaporate me, without any prior warning, if I get exposed to it.... :\
