Babies vs. blind people: two groups with opposite needs. You wouldn’t think so at first glance, but it is true. And the people designing the Stockholm public traffic system clearly favour the visually impaired. Every time I get on a commuter train or the tube with Adrian asleep, a bell goes DINNGG!!!! on the platform when the train is about to arrive, or station names are announced in a clangorous tone. And inevitably Adrian’s eyes also go DING! and he is wide awake. Bleh.
