As white as snow

The weather at Horsey today was just the way I like my winters - cold and bright. A collection of ringed plover and sanderling were feeding amongst the breeding seals. My friend Andy commented on the way the new born seal is white and without stain or blemish but as its experience of life grows it loses the innocence of youth and darkens in colour. There's only one way I know of to return to that state of purity and it doesn't involve a pot of Dulux!
