Happiness is...

... discovering a mysterious fiver in an obscure corner of the organiser-style purse that your mother gave you for Christmas last year but which really has too many compartments so you lose things, when you were convinced you only had coppers in there and need something from the shop across the road but they don't take anything except cash and the nearest cash point is a ten minute walk there and back and it's cold and miserable outside.
Speshly since I wasn't looking for it, I was fishing out receipts to do my accounts on Quicken (yes I am that organised/sad*) .
