I am driving around Cairo and I notice this red bus that is of exactly the same type as the (new) red busses serving London. It even has the same iconic drawing on the side, just behind the driver (imported from the same company, I bet). For a second, my brain merges Cairo with London, superimposing our streets on theirs. But another part of my brain rejects the image. I like them separate.
Another such incident occurred a half hour ago. I have just parked, I open the door and there's a light breeze to relieve my heat. I have Four Tet's remix of "Roads Become Rivers, Rivers Become Oceans" by Rothko on my car system. Perfect music for a hot, 40C day and for me to spot two lizards climbing a wall. They're not exactly the same type of lizards I grew up with in northern Nigeria, but close enough to cause a superimposition, a type of dislocation.
Somewhere out there, everything is still the same.
