My fiancé and I have set a tentative date set for May 7, 2016. However, yesterday my future Mother-in-law reminded me that the day after (May 8) is the day her mom (my fiancé's grandmother) passed away. But by the time my fiancé and I get married, she will have been gone for 5 years. While I don't mind changing it to avoid confrontation, it seems like this is a bigger deal for her than me. Not to mention, while I usually encourage suggestions on most things, I don't think someone should tell the bride when she sould have her wedding.
