When my daughter-in-law Brittany asked me to babysit my grandson Noah for the weekend, I expected cuddles—not an invoice for household supplies. Despite our strained relationship and her obsession with “boundaries,” I agreed out of love for Noah.

Her home was a mess: “no baby food, barely any diapers, and a sink full of dishes.” I cleaned, cooked, bathed Noah, and kept him smiling all weekend.

Then Monday came—with a note: “Please Venmo $40 to cover food, water, and paper goods.” Stunned, I responded with my own invoice: “Grandmother Services, Est. 1993,” listing $200,000 worth of unpaid parenting to raise her husband. After a “99.98% family discount,” the balance left? $40.

I sealed it with flair and dropped it at their door.

Soon after, Brittany sent me the $40 “to settle her debt.” I laughed and donated it to a children’s hospital in Noah’s name.

The best revenge? “Clever and classy.”
