I had made it very clear that I couldn’t lend any money that month, because I still had to put all my money and emotional strength toward the surgery I was about to undergo, and I kept thinking my daughter-in-law would be understanding and stop there. But just a few minutes later, my phone lit up with a message from her, so cold that I was left stunned, unable to believe what had just appeared before my eyes.

I sat at the dining room table with the box, my reading glasses, a yellow legal pad, and the old calculator from the kitchen junk drawer. I went through everything slowly. The apartment deposit. The car repair. The dental work. A check I’d written one summer when they had a gap between paychecks and I had completely forgotten about it until I saw my own handwriting in the memo line. The fence. Two separate contributions toward my grandchildren’s medical bills when copays piled up after one of them had a run of ear infections and the other needed stitches above his eyebrow. Money I had quietly transferred when my daughter-in-law mentioned, almost in passing, that they were thinking about refinancing but weren’t sure how they would cover closing costs.

I wrote it all down.

Date. Amount. Reason.

The legal pad filled faster than I expected.

Forty-seven thousand, three hundred dollars over nine years.

I stared at the number for a long time.
