It's a celebration for those in a relationship or in love. That's not something single people like, I guess. There's also the mass consumerism and marketisation around it, which is the only reason for it, unlike other "holidays" which can be based off religion or tradition. Valentines has just turned into an event based around money.
My guesses, anyway.
Wass. You play minecraft?
Vanilla or modded?
My Valentines Day is going to consist of a picnic style dinner and then going to see A Good Day to Die Hard. And then at the weekend we'll have a proper meal out and then go see Wreck It Ralph and go to a funfair. ^_^
