Well, I can definitely say that was the nearest mission that I've ever done, just 180m from home! When I finally reached Mrs R's we realised that we already knew each other; I've been running past her door and saying Hi for many years, so it was great to catch up and have a really long chat. Mrs R gave me her shopping list and off I went to the nearby Co-op where I managed to get all the items she needed and when I got back Mrs R was very grateful.
