Colour Blind

Amongst the many surprises life seems to have in store for me is the discovery that I am colour blind. I cannot distinguish between blue and green or navy and black. I have several pairs of trousers, some navy and some black. I have worked out a system for sorting them. After looking at the labels through a magnifying glass I have put a small safety pin in the label of the navy ones so that's that sorted. I have been wearing a warm cardigan for some time thinking it was green. I am now told, on good authoity (my daughter) that it is blue.
A favourite card game in the family is UNO where you have to match the colours. Unfortunately when I play there are howls of protest from the grandchildren "No, no Grandma, that's blue" or "No, no Grandma, that's green". I wonder what I look like in my odd colours. Perhaps I should be like the poet and say " When I am an old woman I shall wear purple With a red hat which doesn't go. And I shall spend my pension on brandy". No, perhaps not. Better retain some decorum.
