I once read somewhere a long time ago, (but currently found on the dataguru website) that Beverly Fehr conducted a study in which she described how there are 9 forms of love:
So as you celebrate love today, figure out which form of love you are celebrating. Or which mixture of loves you are celebrating. Today, (this can change tomorrow), I'd go for a heady "love mix" of 50% affection, 20% friendship, 20% committed, and 10% Passionate love these days. Leave me digital valentines of your "love mix" for the day.
