On the way to pick up Mom for her labs and radiation appointment this morning:

Jonah: We're taking Grandma to the doctor again?

Mary-Beth: Wow. She's always sick.

Jonah: No she's not, Mary-Beth. She's not always sick.

Mary-Beth: Yes she is.

Jonah: No she's not.
Mary-Beth: Yes she is.
Jonah: No she's not!
Mary-Beth: (giggle) Yes she is.
Jonah: No she's not infinity!

Mary-Beth: Oh yeah? Then why do we always take her to the doctor? (tongue out at Jonah)

Me: We take Grandma to the doctor for a special medicine she has to use every day. She has something called cancer. Mary-Beth is right, Jonah. Grandma is sick.

Mary-Beth: Oh. (pause) So does she cough a lot? Or sneeze a lot.
