So nice to hear

This afternoon I sat down to do social studies with A&A and, after too many nights of not enough sleep, I could barely keep my eyes open. So as soon as we were done with our reading I laid down on the couch for some quick shut-eye. While "napping" I heard the following:
AJ: "Isn't mom being lazy?"
AP: "No. She deserves a break. She has to get up in the night with D and all she does all day is take care of us."
AJ: "Oh yeah. What would we do without her?"
