Sunday Morning by Judith Viorst, illustrated by Hilary Knight
Mother said good night and father said tomorrow is Sunday and don’t make noise and don’t come in our room. We do not want to hear tie my shoes or give me breakfast or may I watch television. We do not want to hear anything until 9:45 A.M.—and we’ll tell you when that is. Okay I said. See you at 9:45 A.M., whenever that is.
