Falling in love is like a well, good thing to drink out of, but a bad thing to fall into.
Falling in love is a possibility that would never be available to some folks if they had not heard there was such a thing.
Falling in love is marked by a contradiction... namely, the attempt to return to the past and the attempt to undo the past... that is, to re-find parts of the people to whom we were attached as children and to hope that our beloved corrects all of the wrongs that these early parents or siblings inflicted upon us.
Falling in love is the initial experience of love which is to be distinguished from the permanent state of love, which we might better refer to as 'standing' in love.
Falling in love is not something that just happens. One falls in love because of the need, desperate, to fall in love.
