I hadn’t thought about how they are also buying time for their cell phones, how they have purchased units of future which can be exchanged for packets of data-nowness that equate to a connection between people. And as Saeed worries about how cell phone connections are unreliable, Nadia worries about the connection / promise she made to Saeed’s father to stay with Saeed – yet now they wander London separately.
If the fox, as the old lady suggests, is a symbol of their love, and if the fox / love is a noble thing that also roots around in the trash, then perhaps Hamid is saying that even in the trash there are pockets of love, that the animals we see (and that we are because we are “monkeys who have forgotten that [we] are monkeys”) are not animals but expressions of love only. I’m reminded of Bergson.
