It's fair to say that Mrs H's list took a bit of deciphering today, even after we'd run through all the items on her doorstep - top of her list were three bags of Eton mess (these are sweets she explained).

Fortunately from previous experience at the world's politest supermarket I knew where to search for those amongst the aisles, but an item on her list simply called "2x2" proved impossible to find, even with the help of the internet. When I returned with all the other items on her list, Mrs H was so pleased I'd found the sweets that I never did find out what "2x2" actually was...
