Is it me or are pp. 22-23 loaded with sexual tension? First, Lessing (and through the eyes of Anna and Molly) gives so much attention to the way the young man looked; second, the three characters engage in a banter that sounds like what people may say when they explore the possibility of a romance; Molly invites him up; and then the strawberries, wine, and the soft but extravagant description of the light.
And Molly was just complaining about how austere England was! Is she attempting to bring back the sensuousness with the wine and strawberries?
