Love at first sight

In general I don't believe in love at first sight as the first time I saw my actual girlfriend before we were something I even repair on her. Love at first sight is impossible. In a first sight you can only see the apareance so you can only feel physicaly attracted. You can't know the person. But otherwise it's true that there is something else apart from the physic, talking materially, that makes you feel that this person is in a concret way. That would be the voice and what you feel by no-verbal language, the way she moves, her facial expressions... So I think that at first sight you can love that but this anyway doesn't represent the way she is, her personality.
