I discovered that my work colleague had never been inside St Paul's Cathedral - despite the fact that we see it everyday from our office window.
Well that changed today. My 'Friends' annual pass for the Cathedral arrived yesterday and it entitles me to enter with one guest. So our lunchtime walk was around the inside of the Cathedral.
