My sister is getting married in a few months (I am MOH). Her fiance's mom passed away many years ago, so she never met her, but his family is not doing anything for him or the wedding to remember/memorialize her. My family feels we should do something but don't want to cross a line. Any ideas on what my family could do for my sister's fiance specifically? I am looking for ideas different than the standard, ie, something on the program, lighting a candle, etc. Or something the MOB could do for fiance?
