A childhood belief about marriage

I thought that when a boy proposed to a girl, that it was the proper thing to do for the girl to say, "Oh, well, I'll have to think it over", even if she really wanted to say "yes" right away...As a little girl I used to day dream about the time when my future fiance would pop the question and how I would have to go home and be so excited over night, just waiting until the next day when I could excitedly tell him "Yes!!"
