Why carry the Bride across the threshold?

I wanted to share this with you for those that still up hold the tradition! During the days of "Marriage by Capture", the bride was certainly not going to go peacefully into the bridegroom's abode, thus, she was dragged or carried across the threshold.  In even earlier times, it was belied that family demons followed the woman and to keep her family demons from going into the groom's home, she as carried across the threshold upon her entering for the first time.  After that, the demons could not enter as she would come in and go out of the home.

What are your thoughts!?
