You should not need reminding that today is St Valetines day. If you have forgotten until now it is probably too late to redeem yourself.
Christianity has a tradition of hijacking pagan festivals for it’s own purposes and Christmas and Easter are just two examples. St Valentines is no exception, being a christianised version of the Roman festival of Lupercalia. I would not recommend any young men celebrating in the Roman style. Running through the streets naked and striking young women with blood soaked thongs does not go down too well these days.
