For almost as long as Valentine’s Day has been an insufferably sappy day celebrating romantic love, it’s also been a day for telling everyone else exactly how much you don’t love them—with a Vinegar Valentine sent anonymously via snail mail.
“You could send them to your neighbors, friends, or enemies. You could send them to your schoolteacher, your boss, or people whose advances you wanted to dismiss. You could send them to people you thought were too ugly or fat, who drank too much, or people acting above their station. There was a card for pretty much every social ailment.”

So there you have it: Valentine’s Day has always been horrible!
