The Difference Is....

There is an elderly couple in our church and the wife is actually much older than the husband. Her health has declined greatly, and her husband has been taking great care of her. As I was discussing this with the twins the other day I could not help but ask this question of them. I did it separately, as I had a feeling that their answers would be different, and I didn't want their brothers answer to sway what they would say to me...
Me: So, when Mommy gets really, really old, are you gonna help take care of me?

Noah (5): Oh, ya, Mama!

Jonah (5): Um... I think I'm gonna be too busy being a grown-up.

Priceless.
