3.20pm

I was sitting enjoying the view from the top deck of a No.1 when a scream of school girls invaded. The screeches and hoots of laughter beat against my eardrums, the smell of hot school-uniformed bodies assaulted my nostrils (never understand why uniform schools haven't kept up the tradition of swapping to a summer version to try to get teenagers out of blazers and jumpers in July). Play fighting after a day trapped in class. Excitable as the term comes to an end. By the Elephant the numbers thinned and the decibels came down. By Waterloo I was alone once more.
