Even better than working at Bob 's house is looking forward to spending time with a good friend afterwards ; my geographer - friend David came to visit me ! We drank and talked our way through the evening -- a well - fashioned cocktail at Southwark , beer and frites and mussels and beef at Monk 's , a pitcher of margaritas at Cantina Los Caballitos . Monday was the most relaxing day ever ; I basically just laid around , took walks , and chatted about life with David all day . In the evening , I had tea with JLR and beer with Will and talked more about dance and politics , respectively .
