Time is weighing heavily as I sit at my window, sewing. Yes, buttons. Has it really come to this? Every once and awhile I’ll lean forward to wave or nod to a friend or a passing acquaintance. The window washer, the Baptist preacher, the local councilwoman, the `kids’ next door (who are now adults) … We know everybody. But truth be told, it didn’t get off to a good start. My husband Mike Rothschild and I moved into this house in Bow in East London at the end of the first year of the new millennium. Almost immediately we flew to the USA to visit family before returning to begin a massive renovation of our new home.

Which is the most important clock in the world? Many visitors to London would answer ‘Big Ben,’ even though this is officially the name of the bell behind it rather than the clock itself. However, as a London blue badge guide, I would say that the world’s most important timepiece is the John Harrison H4 which can be seen in the Greenwich Royal Observatory museum near where the Prime Meridian is marked on the ground.
