Bedtime conversation with Z

Z: (in whiny voice) Mommy why do you have to work so much?

M: I need to make money so we have a place to live and food to eat.

Z: And water to drink, and to keep the refrigerator door open long enough?

M: (stifling laughter) Yes, honey. Sleep well, I love you.

Z: I love you too; good night Mommy.

Update: Everyone I tell this story to has a blank look until I explain that when Z stands at the refrigerator with the door open, I tell her that an open refrigerator door costs money. She is apparently grateful that we have enough money to get our milk out of the frig for our cereal in the morning. hahahaha
