“Mom, you’re not on the list,” Richard said, and I swear to you, his smile didn’t even flicker.

He was standing at the entrance to Green Valley Estate with one hand on the guest list and the other in his pocket, like he was telling me the restaurant was full.

Not like he was barring his own mother from her granddaughter’s wedding.

I need to back up. Because you need to understand what I paid for before you understand what they took from me.

The cream folder is where this starts. I keep it in the bottom drawer of my study, in the apartment on the Upper West Side that Robert and I bought in 1986. Robert was my husband. He died 7 years ago. Heart attack at his desk on a Tuesday.

After he died, I kept the apartment and I kept the files. Robert was meticulous about paper. He taught me to keep copies of everything, and I do. Tax returns. Insurance policies. Receipts over 500 dollars.

So when Clara called me in January and told me she was getting married, and my heart nearly burst, and she said, “Grandma, will you help me plan it?” I started a new folder.

Cream colored. Tab labeled: Clara’s Wedding.

Clara is my only grandchild. She’s 26. She works in marketing. She has her grandfather’s eyes and her mother’s ambition and my laugh, or at least she used to have my laugh.

I didn’t help plan the wedding. I funded it.

Let me just be honest about the numbers, because I keep going back and forth about whether I should have said no.

The venue at Green Valley Estate: 28,000 dollars. The caterer: 19,500. The florist: 12,000. The photographer and videographer package: 8,400. The string quartet: 3,200. The lighting upgrade Susan wanted at the last minute: 6,800.

Invitations, the cream stock with the deckled edge Clara picked out at my kitchen table: 2,100. Dessert table. Valet service. Linen upgrade. Miscellaneous vendor deposits.

Total: 97,400 dollars.

I wrote every check. I signed every contract. The vendors had my phone number, my email, and my signature on file. If something went wrong with the tasting menu or the table arrangement, they called me. Not Richard. Not Susan. Me.

Am I crazy for thinking that means something? Tell me if I’m crazy.

Clara came over every other week during the planning. We’d sit at my dining table, the same table where she used to do her homework after school, and go through the binder. She wanted the ceremony under the stone arch at the estate. She wanted white roses, not cream. She wanted the quartet to play Debussy during the processional because Robert used to play it on Saturday mornings.

“It has to feel timeless, Grandma,” she said, holding up two invitation samples.

“So let’s make it timeless,” I said.

I thought I was building a memory with my granddaughter. I thought we were doing this together. But somewhere during those 6 months, while I was calling florists and approving linen swatches, Susan was doing something else.
