Sure: today is Saint Valentine's Day. Love, love, love.
I won't write much because I meed to get on with a little romantic brunch, so see the listing at the Patron Saints Index. An excerpt:
Others maintain that the custom of sending Valentines on 14 February stems from the belief that birds begin to pair on that date. By 1477 the English associated lovers with the feast of Valentine because on that day "every bird chooses him a mate." The custom started of men and women writing love letters to their Valentine on this day.
Which makes me think of this entry my friend Terrance blogged about.
