Lately, I've frequently been reminding Calliope to cover her mouth when she coughs or sneezes.
And so now when I sneeze (and dutifully cover my mouth), Calliope calls out cheerfully, "Bless you, Mommy!"
Then comes running over a few seconds later, claps her hand moistly over my mouth for a moment, then looks at me intently and says,
"You're welcome, Abby. You're welcome."
