how to tell your in-laws that one does want to hold wedding dinner. my sis has already ROM for a year and has gotten their own house but her mom-in-law kept chasing them to hold a wedding dinner.

my sis does not want cause she said it's going to cost alot of money she don't see the need to spend this kind of money but at the same time do not want to offend the in-law. you know lar difficult leh.
