CMV: There is no such thing as "love at first sight"

So-called love at first sight is based on just that - sight. 
&nbsp;

Now I know some people are going to jump in with anecdotes about grandparents who married after three dates and were together for 70 years and whatnot. But that is a form of commitment and usually (in older people) a response to a society that did not really allow for divorce. Can two people make it work if they fall in love based on sight and quickly marry? Sure, sometimes. But that doesn't mean that real love, deep love like you have when you know all parts of a person can form immediately upon seeing them. You can't truly love someone without knowing about their personality, their thoughts and their feelings.

Don't you think that if someone who is in love comes and says to you they fell in love at first sight is, at minimum, extremely presumptuous of you, someone who can have no idea how they feel, to question it?
