Every minute that we refuse to love one another, another puppy cries another tear. - Dr. Gregory House, on what would happen if there were to be no Valentine's Day.
Women are like wolves. If you want a wolf, you have to trap it. Snare it. Then to keep it happy, you have to tame it. Feed it, care for it. Lovingly. The way an animal deserves to be loved. And my animal deserves a lot of loving. - Dwight Schrute, on keeping a woman happy for Valentine's Day.
Valentine's Day (more properly Saint Valentine's Day, but no one usually remembers this) takes place on February 14th and is a commonly known date for general assumed romance.
As a result of this, during the week of Valentine's Day, many poorly written out romance one-shots and smutfics are uploaded.
It is not a happy season for singletons or people not especially interested in reading poorly written romance fics. In fact, many people tend to rebel against Valentine's Day and wear any color but red, white, and pink.
Alternately, it is a good midpoint for the intake of chocolate, as it is situated right between Christmas and Easter, two other large holidays for the partaking of chocolate (though it has been observed that one may buy more chocolate for less money on the day after Valentine's Day).
