My parents were coming over to visit, and to take the "bigger kids" out to the playground. From the way, they called to say that they wanted to change plans and take the kids to the beach instead (more time for me to rest with the baby!).
As I raced around packing different gear, changing clothes, and applying sunscreen, Ann (4) remarked, "You're very responsible, Mom!" [Since when did I become 'Mom'?!]
"You're welcome, Mom."
Five minutes later:
Ann: "What does responsible mean, anyway?"
