Kevin....."Love, at first sight," I am sure, is merely a figure of speech. It normally means that "attraction, interest & other good emotions," were at a high degree, when we first met someone. These feelings may cause us to be drawn to this person, in an effort to get to know them better and a desire to spend more time with him/her. However, I also believe that these initial feelings and reactions have a validity and a power. If we are "instinctively" quite seriously drawn to someone, chances are there are things at work here, that we may not even be aware of.
To be honest with you, if I think back 46 years ago, I can distinctly recall the moment I met the man who became my husband and father of our 2 sons.....when our eyes met and he smiled his outrageously gorgeous smile, I was BONKERS!....GONE.....Hypnotized.........Could I and did I use the phrase, "Love at first sight?" I sure did. But the reality is, it actually took me the better part of an hour to really FALL IN LOVE.........LOL....good question
