表语从句
Most people get married believing a myth--that marriage is a beautiful box full of all the things they have longed for:
companionship, sexual fulfillment, intimacy, and friendship. The truth is that marriage, at the start, is an empty box. You must
put something in before you can take anything out. There is no love in marriage; love is in people, and people put it into
marriage. There is no romance in marriage; people have to infuse it into their marriages. A couple must learn the art and
form the habit of giving, loving, serving, praising--keeping the box full. If you take out more than you put in, the box will be
empty.
