When my mother-in-law, Barbara, turned sixty, she didn’t want a restaurant or a hall. She wanted “intimacy.” Specifically, she wanted to host her milestone birthday at our house—a restored Victorian with a professional-grade kitchen and a garden that looks like a Pinterest board.

I spent three weeks preparing. I’m talkng hand-lettered place cards, a jazz trio playlist curated to her exact taste, and a five-course menu. I even tracked down a bakery three towns over to recreate her “dream cake” from a vintage photo of her childhood. My husband, Mark, was appreciative but kept giving me a wary look. “You don’t have to do all this,” he’d say. “She can be… a lot.”
