Youngest (a young woman now!) is very aware of time and passages right now -- today is her last day of childhood, or at least, of elementary school. She graduates from 6th grade today and is then officially in Junior High!
She told me the other day: "When I'm old, like 50, I want to be like you. And also like my teacher, Mrs.A -- she's training for a 50 K now. For both of you, exercise and health are important, and you don't feel old. That's how I want to be!'"
What a compliment!
I turn 50 this year (disclaimer: I am not training for a 50K), but I do keep active, and I certainly don't feel OLD.
Digression: My grandmother, when she turned 50, stopped wearing a bathing suit in public! She would have considered it "indecent exposure"!
