it depends what you mean as love cos, i think you can really like someone to a point you feel like you love them but in ma opinion i dnt thing love at first sight is straight away real love except u spend a bit of time with some one e.g a guy felt in love with a girl the first day he met her but after a couples of weeks and she refuses to sleep with him he then stop calling, so at first, it wasnt love, is just that he really did like her at that moment
