not a "decoration" issue, but my halloween tradition has always included (as a response to the gluttony promoted by the candy industry) a plea
for help fopr those who do not have candy, or even the necessities.

Trick or Treat for UNICEF is a great way to share on halloween.

if kids go door to door asking people to help with food, shelter, medicine and clean water for those in need, it is a good lesson
for all involved.

I have often had a booth at the school carnival with face painting
with donations going to UNICEF
