CONFUSIONS OF VALENTINE

Hello guys! Its Valentine's day or that is what almost everybody around says, and they all got big plans, they wanna celebrate, but hey Valentine was a priest and from the little I know of him;

1: he did not declare declare free sex for singles

2: he did not give or support the excessive consumption of alcohol

3: He did not propound the theory of gifting singlet and boxers, pant or bra on 14th Feb, or any other day to anybody

4: he never said Red and white colours must be worn in his memorial

5: he never said no iphone no love

6: he never forced anyone to an expensive dinner...

So can anybody please tell me just who the hell are we celebrating on 14th February????
