Give it to the Japanese to make a festival out of everything; in this case, Halloween. A party made for the foreigners in my city, with performances from around the world, green tea and the best of all - paper airplane making - you can understand how much I like making those by the fact that there isn't a single picture of one.
Such social gatherings are dearly missing in some of the countries I've been too. And no, going to the local bar or some concert isn't a replacement. At least, not for me.
On one occasion I actually managed to get bored for a moment, which actually says a lot about how much of an observer I have become thanks to photography. Didn't last long though, too many amazing people there.
