I was sure glad I wore my step-ins today

I took my new grandson to his pediatrician visit this morning and when we got back home, my granddaughter Kerra said, nana I can see your underwear!! I said what??? My very favorite pair of worn our Levi's had developed a rip at the back pocket haha. Imagine my embarrassment if I had not put on my step-ins and Kerra said ...Na Na I can see your butt cheek
Ps.. Step-ins old mountain term for underwear
