I was never the “quiet knitting” kind of grandma — more the roller-skating, midnight-salsa, puppy-yoga type. At 79, I still wanted a bigger to-do list. My favorite “adventure” was Jason, my grandson, who I watched almost daily while my daughter-in-law, Kelly, had “stuff” to do. My son Jack thought Kelly was supermom, never realizing I kept the house clean and Jason happy. When Jack started sending me extra money, Kelly’s smile got tight. I overheard her once: “If he keeps sending her that much, I’ll never get the…” She stopped short, but I knew something was brewing.

At my 80th birthday picnic, Jason gave me a pink scooter. We rode off, but when I turned for ice cream — he was gone. Kelly pounced: “See? She can’t handle it!” Moments later, Jason popped out from under a blanket, giggling, “Mom told me to hide from you.” Soon after, I saw Kelly’s Instagram post with “@nanny.nina.”

I met Nina, paid her a month’s wages to have a “family emergency” the day Jack and Kelly left for vacation. Jason spent the summer with me — pies, museums, adventures. When Jack returned to a spotless house, he finally saw the truth. No one could out-grandma me.
