In my schools everyone either had to give valentines to everyone or to no one at all, which reduced the opportunity for genuine sentiment. In my recollection at least half the point was the candy that almost everyone gave out with their valentines. Though I do remember making very careful choices about which of my classmates got which valentine message out of the box of cards.

But, you know, now that I think about it, I can totally see why it would be weird. It is weird.
