When my father died, my sisters decided they couldn’t hold the service for him right then because there was a birthday in that month, there was a holiday in the next month, so on and that they didn’t want the kids to associate the birthday / holiday with grandpa dying.

The problem was it left the rest of us in unresolved grieving for 3 months.

Family is hard to please, but I’d serve the new potatoes unless your mother has said something about new potatoes.
