"Stereotypes are ways of making extremely primitive and simple differentiations. Differentiations of gender, race, class, social status - so ordinary social life is very much built upon a whole repertoire of stereotypes we carry around. And those are immediately laminated onto people, and it isn't just visual."

I'm sorry, but I do hate this differentiation between the sexes. The modern girl has a thoroughly businesslike attitude to life! That sort of thing. It's not a bit true! Some girls are businesslike and some aren't. Some men are sentimental and muddle-headed, others are clear-headed and logical. There are just different types of brains.
