During a visit to the Washington D.C. area, I took the Orange Line of the Metro into the city. It suddenly dawned on me, how confused a non-English speaker could be, when faced with these transportation signs. I immediately thought of the automated ticket machines in Paris, for non-French speakers, as a comparison. We tend to take it for granted that things are easy, so I tried to put myself in someone else’s shoes – as a type of role reversal. Have you encountered this type of situation?
