V-Day

I don't understand why girls expect flowers and candy on Valentines Day. It is just another day. A card is nice but I don't see why they actually get upset when their boyfriend doesn't have a dozen roses delivered on V-day. We had a girl in our office throw a hissy fit because she didn't get flowers and some other girl did. What is the big freakin' deal? I have never really understood Valentines Day anyways. It's stupid. Calm down ladies.
