Valentines Day, also called Saint Valentines or the feast of Valentine is today! You probably are aware of that with the subtle increase in advertising of roses and Chocolates.
In Europe, Saint Valentines Keys are given to lovers "as a romantic symbol and an invitational to unlock the givers heart" Which is pretty much the most vomit inducing thing I've ever heard of.
To the people that aren't celebrating it, don't sweat it. It's no biggy! To those who are, have a good day and perhaps a good night too ;-)
