Modern Primate partner site 11 Points has a great list of random facts about today.
February 29th is the one day where women are traditionally expected to propose to men. And not just in Amy Adams movies. This actually is an Old Country (who knows which Old Country) tradition. And if the man turns you down, he’s supposed to give you cash or clothing. Seems like a fair tradeoff for an eternity of humiliation, shattered self-esteem, and futile attempts to find someone who wants to buy a second-hand, unlucky engagement ring sized for a giant man-sized finger.
