Particular perfection

An interesting excerpt about marriage I read today:

I've never forgotten a nervous bride-to-be asking an older friend, "I love Richard with all my heart. But how do I know that later on I won't meet some man who has lots of qualities that Richard does not have?" Her friend replied, "Undoubtedly you will--lots of them! But the point is that they won't be Richard!"

Perhaps a slightly different spin on it is that you aren't looking for someone perfect when you want to marry, but someone perfect for you.
