4. You can decorate for Valentine's Day because, unlike Christmas decor, there is no popular public opinion as to when is too soon to put up the cherubs and pink and roses and ribbons and pretty china (my every day decor is somewhat indistinguishable from my Valentine's Day decor, 'tis true). However, I am willing to own that there might be plenty of private opinion. You can make yours public here if you like (but be gentle as I put my Valentine's decor up before I finished taking down Christmas).
