Re: how would you feel?
You gotta think about it like this.
After her marriage day, you have no clue how her marriage will work out. She could be going in for helll, for all you know.
So maybe, her marriage day will be her only happy marriage day.
Its in your best interest as a friend to pamper her to the extreme, so that she can at least have that one day to look back on in happy memory of her marriage life...
