There are three possible parts to a date, of which at least two must be offered: entertainment, food, and affection. It is customary to begin a series of dates with a great deal of entertainment, a moderate amount of food, and the merest suggestion of affection. As the amount of affection increases, the entertainment can be reduced proportionately. When the affection IS the entertainment, we no longer call it dating. Under no circumstances can the food be omitted.
You will notice that what we are aiming at when we fall in love is a very strange paradox. The paradox consists of the fact that, when we fall in love, we are seeking to re-find all or some of the people to whom we were attached as children. On the other hand, we ask our beloved to correct all of the wrongs that these early parents or siblings inflicted upon us. So that love contains in it the contradiction: The attempt to return to the past and the attempt to undo the past.
