We had the following conversation last night with our four-year-old daughter, "DG," Dixie Girl:

DG: Right Hashem can't see us because He is deep inside our hearts?

Mommy and Daddy: No, Hashem is everywhere so He can always see us.

DG: So then He's also in our hearts?

Daddy: That's true.

DG: So it's like I said!

Such a good girl! And also quite literal - shows how careful we have to be about how we teach things. :-)
