(Valentines & Waifus!)
Among the single nerds/geeks/weirdos/outcasts, I think otaku are the only ones who seem to actively celebrate Valentine's Day. Figure.fm is flooded with celebratory posts.
Personally, I can't really get into the idea of buying a ridiculous amount of expensive perishables (flowers, cake, candy) for a waifu who can't use it anyway.
... But I can understand an INexpensive perishable. ^_~
Happy Valentine's Day!
