Dear Prudence,
My granddaughter “Riley” is getting married late next year. She’s currently putting together her guest list (I heard this through the grapevine) and is not planning on inviting my childhood best friend, “Greta.” Greta has been overwhelmingly kind to Riley for over 30 years. She sends Riley checks for every birthday, takes Riley to dinner whenever she’s in town, and generally plays a grandmotherly role in Riley’s life. I hadn’t heard of any conflict between the two of them. But it appears that Riley has forgotten all of this as she builds the guest list. She and her fiancé are getting financial assistance from my son for the wedding. It seems cruel to not include Greta when it’s not even Riley’s own money! I’m thinking of putting my foot down and saying I won’t attend if Greta doesn’t attend either. Greta’s been mercifully quiet about this, but I can tell she’s heartbroken. I would be too. What’s a grandmother to do?
