Today is the day where men send roses to the ones they love.
But it wasn't always like that because today is the day when the slaughter/martyrdom of a number of guys unlucky enough to be named "Valentine" (or Valens, or Valentinus). I suspect that if they'd changed their names, their fates would not have led to such an unfortunate fate on such a date as this one. ;^)
And who can blame men for taking out the demand for chocolate covered strawberries, wine, wine glasses, a fancy meal, flowers, etc. that is levied on them on this day? Heiromartyr Saint Valentine (Bishop of Interamna, Terni, Italy), Saint Valentine the Presbyter, (St) Valentinius, a Roman who died in Africa and the Greek Orthodox Saint Valentinios could have all led happy and productive lives if not for their advocation of fancy dinners. Do you know how difficult it is to get a dinner reservation on THEIR day? Do you know how frustrating it can be for men - men who are threatened with the prospect of being 'cut off' if they don't observe the day?
If you took a poll of men (hooked up to a polygraph so their integrity wouldn't be questioned) and asked them what fate all of the St. Valentines deserved, I'm guessing that they'd say, DEATH!
During the Great American Depression, things got so bad that the St. Valentine's Day Massacre took place as men fought for prime seating at peak hours at one of Chicago's most exclusive restaurants. At least that's my take on it. There are other interpretations by people who wanted to sensationalize the spontaneous battle as a "gang fight", but we all can discern the truth.
