Do you believe in "love at first sight"?

i do not believe that love at first sight exists. i believe that passion at first sight exists. because you cannot truly love someone that you do not know how he/she thinks or feels about what is important ot you or if it's the person that you want. but you can be so atracted by a person that you see for the first time that you might think that you are in love. but i believe that this is only passion and if the peson is right for you love will come aftre but you will never observe that and that's why some people say thay they fell in love at first sight
