Do you believe in love at first sight?
I just finished a book about a woman who fell in love with a monk (who was, obviously, not her husband) the first time she saw him. Apart from the whole infidelity thing (which also bothered me), I had a hard time believing that the man and woman fell in love after meeting each other only once. I can understand if they had spent an afternoon together or an evening, but one meeting? Seems to me that love at first sight is really just lust. Nothing wrong with some good old-fashioned lust, though.
Granted, I am biased. I met Doug at the first Lollapolooza concert, when he came walking by our blanket with his friend Mike, who was also my friend Mike. I don't remember anything special about the meeting except that I met Mike's nice friend and hung out with them on their blanket for a while during the afternoon. It was only through repeated exposure over the next year or so (same friends, same concerts, same parties, he liked my scar) that I realized that Doug was as great as he is.
I just don't think you can realize the fullness of someone else at first sight.
