so where've you been? 15 London

Ain't that a surprise? I went home for a brief holiday - a holiday from my holiday - and found that it isn't my 'home' any longer.

There are three certainties you need to keep up the robust sense of self that allows you to travel. To really travel, rather than tick off sights.
1. Know who you are.
2. Know why you're going.
3. Know where 'home' is.

It took me exactly four minutes to realise I'm not a Londoner any more.
