What do I do? My Grandmother sent back her RSVP with a "sorry I can't make it." My dad offered to pick her up and take her home ( she is 85 and lives in Las Vegas) mind you she still spends her nights smoking drinking and gambling up to 2am. I did visit her in May and at that time her companion didn't even know we were getting married... I did call her which she ignored and hasn't called back. What should I do my dad will not call her and ask why she can't make it... do I let it go?
