The Pleasures and Sorrows of Work - Alain de Botton
I just booked to go and see Alain de Botton speak on The Pleasures and Sorrows of Work at the Opera House (see here if you are interested – selling fast) with a small group of friends from work. I quite like his work (from a human interest perspective), so do they, and Status Anxiety included some positive references to Christianity (from memory!), so perhaps it might open up some conversation.
My bible study group is encouraging us to be proactive this year about engaging with our non-Christian friends, and also including the rest of the group in doing so, and these work friends are on my hit list :). That and it should just be something interesting and fun to do!
