My father took me on a bus past Blackwall Tunnel - a Victorian road tunnel under the river Thames with an imposing building above the entrance. "See that" he said "that takes people all the way under the river" For a long time I thought that the windows and doors were closed and the whole building slid down under the river, like some kind of submarine ferryboat.
