Weddings in the United States vary as much as the people do. There are church weddings; there are weddings on mountain tops with guests barefooted; and there have been weddings underwater on the ocean floor. But many weddings, no matter where they are performed, include certain traditional customs. Before a couple is married, they become engaged. And then invitations are sent to those who live nearby, their close friends and their relatives who live far away. When everything is ready, then comes the most exciting moment. The wedding itself usually lasts between 20 and 40 minutes. The guests enter the church first while the wedding music is played. The bride carrying flowers enters last with her father who will "give her away". The bridegroom enters the church from a side door. Then the couple will exchange their solemn promises to each other. It is traditional to use the words "To have and to hold from this day forward, for better, for worse, for richer, for poorer, in sickness and in health, to love and to care, till death do us part". Following this, the couple exchange rings. Wearing the wedding ring on the fourth finger of the left hand is an old custom. After the ceremony there is often a party, called a "reception" which gives the wedding guests an opportunity to congratulate the newly wedded couple. After all the procedures, the couple runs to the car under a shower of rice thrown by the wedding guests. And then the couple just go on their honeymoon.
