not true. A wedding is an event for both wife and husband.
Although asian tradition tells us the husband should be footing all
expenses, it is only right for both parties to share the
cost.
remember, the wedding is the first "project" that the wife and
husband will work together for.
in western cultures, the bride's family will pay for all events,
the groom and his family sole purpose is to grace the event and
promise to take care of their new daughter throughout the new
marriage.
