Mmm... It does and it doesn’t

I believe a lot of people mistake lust for love. So falling in love with someone's appearance at first sight seems a little shallow to me. But I do believe you can know someone's the one after the first date or after meeting them at a business meeting/etc. I've seen that happen to some people I knew. So I guess my statement is that you cannot fall in love with someone and their whole being (like their personality and everything else that makes up this person) with just one sight. But I do believe you can feel that love connection after meeting just once, even if you don't act on it until further in the future.
