In the film Exotic Marigold Hotel, the character played by Judi Dench takes off to India, newly widowed and escaping from her London life.  As she strides through the airport before catching the flight, her son is showing concern about how she will get on and how they will communicate.  'Don't worry, read my blog!' she replies over-confidently - and gets a laugh from the audience.  When we saw the film, my daughter said 'That would be you."  "Hardly" I thought, "I wouldn't have a cat in hell's chance of knowing how to begin to blog....".
But golly, here I am - learning.
