Laugh as much as you breathe and love as long as you live

Can you tell me,How can one miss what she never had,
How could I reminisce when there is no past,
How could I have memories of being happy with you,
Could someone tell me how can this be

When i think that everything is going wrong.. i look at her and wait for that kiss.. then when she leaves my car i look at the rear view mirror and i saw her look back.. it assured me that maybe we will be ok
