Gramma Carrie? Is she a stepmother? Maybe I missed something. Gramma is Gramma no matter if she’s Lynn’s or John’s. It just sounds so disrespectful. Maybe it’s just my generation.
My cousins (both blonds, back in the early 1960’s) did that and their hair was just a soft misty green. I was just a kid and they were much older, I thought it was the most beautiful shade of green. Between my comment above and yours, I am having a great trip down Memory Lane.
The third way will throw you a curve.
