Diary of a postman.
Round About Town is a hugely entertaining book. It comprises the diary entries of Kevin Boniface, a Huddersfield postman. It’s packed with observations and overheard conversations. I frequently found myself laughing out loud. (I don’t mean that simply as an expression; I actually did laugh out loud many times.)
Boniface’s words are augmented with equally well-observed photographs gracing every double-page spread.
If Alan Bennett were a postman, his diaries might read very much like this. (And they wouldn’t have all that boring stuff in them about the theatre.)
