Me: Bree and Cate, time to start our school for the day.
Bree: *groans* Why do I have to do school all the time?
Me: So that when you grow up you can get a job because you may want to buy a house of your own someday.
Bree: But I would miss you too much! Why would I want to do that?
Cate: Mom, I want to live with you forever!
Be still, my heart. I wish I could keep them with me forever, too. Or maybe I can talk them into just living down the street. 
(And now I also feel a little bad for moving so far away from my own family when I grew up.)
