What did Miss Thomas tell Bud to keep in mind?

From the text:

"Before that grin gets stuck on your face, let me tell you you're going to have lots of chores and things to take care of around here, Bud, you'll be expected to pull your own weight the best you can. We all like a very clean house and none of us are too used to having children around, so we're all going to have to learn to be patient with each other. There's one person in particular that you're going to have to be very patient with. Do you know who I mean?"
