Strolling through Liverpool Street today trying to have a conversation on the phone, and cradling it to my ear because the speaker has gone faint again and holding a box on my shoulder with the other arm. Hot work on a humid day and I had to give up on it eventually. I deposited my box with the pleasant lady in reception then bopped to Pret for the breakfast sandwich. Thus revived I was free to spend the afternoon browsing spreadsheets in semi bemusement. What was I doing and why?
