" Mrs. Carter and Mr. Carter are very nice! It is only that you need to show respect. They will tell you to call them “Cate and Ted,” very American, very equal—but it is always “sir” and “ma’am.” They will tell you to “make yourself at home”—but they do not want you to make yourself at home! Because it is their home, not yours, and they are not your friends. They are your clients. Only that. "
