The "Joy" of a Much-Younger Sister

A conversation between my daughter Katie Beth, who is 21, and my caboose kiddo Christa, who is 7:

Christa: Katie Beth, when I grow up, I am going to have a car and a motorcycle!

Katie Beth: Well, I'll borrow your motorcycle all the time.

Christa: No you won't! You'll be too old!

Katie Beth: How old do you think old is, Christa?

Christa: Like 90.

Katie Beth: When you start driving, I'll only be 30.

Christa: Well, yeah--you'll still be old!

Of course, Christa did not share her plans about having a motorcycle with me. And if 30 is old, I don't know what she thinks I am--besides tired.

And Christa doesn't know that Rob and I plan on her brother and sisters teaching her to drive. So she'd better treat them nicely and not razz them about their age.
