We don't have Valentine's day here. People here celebrate the "Day of Friendship and Love", with emphasis on friendship, and play "Secret friend", a variation of Secret Santa with set gift types over days and not on Christmas. Also, it's not something sanctioned and with a lot of merchandise centered around it, it's just a thing people do.
Confession: I use my tablet in classes when I'm not paying attention. I wish I were a better student than I am, but 3 hour classes are not quite so comfortable.
