That's so cute. You always have to watch what you say in front of the little ones don't you?
I'm 62 and have a few gray hairs at my right temple area. I haven't decided whether I'll dye my hair or not.
Both my daughters tease that they want "my hair genes" rather than their father's. This is because my side goes gray late. My grandmother was salt and pepper into her late 80's, my mother had mostly dark hair with a gray stripe going back from her right temple area when she passed at 77 while the girls' father started going gray in his 30's and his mother was totally gray at 30 when I first met her.
