Mother would never in a millions years have let us ride the subway in New York.  She never did.  Even with our nannies we would take the bus or Mother would give them cab fare.  But after only a year in London, Robbie and I were riding the Tube or the Underground everywhere — by ourselves or with a pack of other kids from school.  Busses were fun but the Underground was fast and filled with cool people and round and much cheaper than taking a taxi.

And when you’re saving all your money for platform shoes and trips to Biba, that’s an important difference!
