Should love just end at the first furtive glance, the first eye contact, the first hint of a smile as the eyes meet? The thoughts, as you realize for the first time after seeing a person that you are in love, are pure and free o any negative bias. There is no feeling of hatred, burt or jealousy, all there is, is the realization of love. You look at them and you see them as you want them to be, you perfect vision of your partner, without the biases of any outside influence. They are yours to imagine how you want the to be, your fantasy taking shape as per your desires.
It is an imperfect moment made perfect by the YOU. That's where it should end.
