Look Emily, love at first sight may be real, only you know your experience so far be it from me to tell you that you don't know your experience.
But please don't fucking tell people that if they didn't experience "love at first sight" they don't know "real love". My love for my soulmate developed from friendship. And it's just as mystical as yours and just as deep thank you very much. OK?
As you say yourself "I know what I know".
