"Repetitive pictures of gray pears on the grimy walls of Victoria Station advertised the bath soap English governesses had used upon me in my childhood"

Here is a perfect example of the way one can shape one's own memories and associations. Compare this line to the one on page 63, where Nabokov is boasting of his family's Anglophilia and its use of imported English goods: "Pears' Soap, tar-black when dry, topaz-like when held to the light between wet fingers, took care of one's morning bath". On page 195, the Nabokov family are suddenly refugees, on their way to Europe, through London, and contexts have all changed; soap, that most evocative of products, is now the vehicle of anti-climax as the new reality of their life dawns.
