此外，有鉴于本书的主题与立场，我必须诚挚感谢我们家那完美的保姆群，让我那过分紧凑的工作时间得以顺利推进，从一开始的悉妮·范尔斯（Sydney Viles），然后是比利、侑拉、凯莉等许许多多了不起的年轻女性与男性。
我也要对我的母亲芭芭拉献上最诚挚的感谢，她长期作为编辑所累积的知识，提升了本书的质量，而她自身的写作、女性主义学术成就与早期为了同时进行工作、创作与身为母亲所经历的挣扎，也成为我的灵感来源。
最后，我要将毫无保留的感谢，致与我的先生彼得·玛斯（Peter Maass），还有我的女儿克莱奥·奎特·玛斯（Cleo Quart Maass）。对你们的爱，促使我想要动笔写下关于其他家庭、还有一点点关于我们的故事。
