I am sat here time wasting. I have tried to be scientific and work out when Waitrose will be the least busy today. I think over lunch time? Hence my time wasting before I set off. But I am totally dreading doing the Christmas food shop today. Furthermore I shall also have to go via Tescos to stock up on the value stuff - so that's two supermarkets in one day, the 23 December. However, there is one silver lining - I don't have to drag any children around with me! Skips.
